Vehicle Identification Number (VIN) Decode

          12ebbYPxxxxxx    e.g. 124379N506070
 where
      1 = Chevrolet
      2 = Camaro
      e = 3  for 6-cylinder engine, or
          4  for 8-cylinder engine
     bb = 37 for coupe body, or
          67 for convertible body
      Y = 7  for 1967 model,
          8  for 1968 model, or
          9  for 1969 model
      P = N  for Norwood, OH assembly plant, or
          L  for Los Angeles, CA assembly plant 
 xxxxxx = vehicle serial number sequence

 At each plant, the vehicle serial number
 started the year at the following number:

    100001 for 1967 models
    300001 for 1968 models
    500001 for 1969 models

If the first car off the Norwood line in 1968 was an 8-cylinder coupe, then the VIN for this car would be 124378N300001. The next car would have been 12xx78N300002 (the xx would be dependent on whether it was a L6 or V8 and a coupe or convertible). The first Camaro off the Los Angeles line in 1968 would be 12xx78L300001.

Norwood produced more than 100,000 Camaros per year, so the VINs would continue to increment to 12xx77N200000, 12xx78N400000, and 12xx79N60000, etc. The monthly VIN list shows the range of VIN's used at both plants.

In 1967, the VIN plate is located on the driver-side A-pillar (front pillar) and is visible when the driver-side door is open.

Starting in 1968, and continuing to the present time, the VIN plate was relocated to the upper dash panel, on the forward portion of the drivers side, and is viewable through the windshield glass when standing at the front edge of the driver's door. The location is shown in this photo.

Starting in August 1969, the complete VIN was also stamped on a conformance sticker that was placed on the driver's door, just above the door striker.

The VIN does not provide any information other than what is listed in the box above. The VIN does not tell if the car is a Z28, SS, RS, etc.

Partial VIN Definition and Location

In addition to the official VIN plate, a partial VIN should be stamped on the body sheet metal in two places:

1. On the cowl in front of the passenger side (underneath the cowl vent panel). You can see it sometimes if you carefully look with a flashlight through the slots in the vent panel, but the panel comes off with a few screws and the wiper arms pop off pretty easily, so this one is not a big deal to get to. The photo below (with the cowl vent panel removed) shows the typical location for this stamp.
2. On the firewall below the fan motor opening (non-AC cars) or below the heater opening (AC cars). This requires the heater or air conditioning box removal, and therefore most car buyers will not have an opportunity to view this stamp. The photo below of the passenger side of the firewall shows the typical location on a car without air conditioning.

Cowl Partial VIN	Firewall Partial VIN

The format of the partial VIN is:

            YPxxxxxx (1967)     e.g. 7L102030
           1YPxxxxxx (1968-69)  e.g. 18N304050 
 where
       1 = Chevrolet
       Y = 7  for 1967 model,
           8  for 1968 model, or
           9  for 1969 model
       P = N  for Norwood assembly plant
           L  for Los Angeles assembly plant 
  xxxxxx = serial number sequence

Partial VINs were also stamped on most engines and transmissions from 1967 on. Not all engines and transmissions in 1967 were stamped with partial VINs. Details and examples are shown in the Drivetrain Decoding section. However, be aware that the partial VINs can be "restamped" on engines and transmissions by machining off the original stamp (or finding one that is unstamped) and then stamping the desired VIN.

12337 VIN vs 12437 Cowl Tag Code

The 3rd digit of the VIN identifies which engine (L6 or V8) the car had from the factory. A VIN engine digit of 3 indicates a L6 engine, while a VIN engine digit of 4 indicates a V8 engine.

The cowl tags for 1967 Camaros were stamped with a style code of 12x37 or 12x67, where the x was set to 4 for standard interior or 6 for custom interior. All 1968-69 Camaros (L6 or V8) had a style code of 12437 or 12467 on the cowl tag - the 3rd digit of the firewall style number for these two years was fixed to 4 and effectively had no meaning.

For related information, see also the Cowl Tag and Numbers Trivia sections.

(These discussions apply only to U.S.-built bodies sold by GM in North America and are not applicable to models assembled outside of the U.S. Note that 1968 Yenkos and 1968 non-Canadian export models, not requiring the statement of certification to the Federal Motor Vehicle Safety Standards, were shipped with 1959-1963 style Fisher Body tags that are absent the 1968 certification statement. 1969 export tags are also blank on the bottom of the tag.)

  Field a - body build date code

This is composed of two digits (01 thru 12 corresponding to each month of the year) and a letter (A thru E corresponding to the week of the month) and indicates when the assembly of the body was started. For example, 11C means the body assembly was started during the third week of November of that model year. 05A would mean the body assembly was started during the first week of May.

  Field b (LOS vs NOR)

LOS - Fisher Body body scheduling code

The LOS (Los Angeles/Van Nuys) body scheduling code is a letter followed by one to three digits, e.g., F103. Based on data analysis (there is no GM documentation that describes this code, but the data is consistent across thousands of datapoints), CRG believes the code was used by LOS Fisher Body (and other plants that built multiple carlines) to aid in scheduling the body build order.

The letter indicates the approximate day of the month for the start of the assembly of the vehicle body. It is only an approximate date because it appears that the day on the tag was actually when the vehicle was being scheduled to be built. The actual start of production could vary by a few days.

The code began with letter "A" on the first day of the month of the Fisher production calendar, incremented at the start of each additional production day to the next alphabetic letter, and was reset to letter "A" at the start of the next production month. (Note that the Fisher production calendar is known to differ from the calendar month, and we also do not know exactly how the Fisher production calendar related to the Chevrolet monthly production reporting calendar.)

The one-to-three digit sequence number that follows the letter was reset to 1 at the start of each day and generally incremented serially with each body built by the factory as the day progressed. Due to scheduling requirements, this progression was not absolute and vehicles chould be built out of tag sequence. Data analysis indicates that the sequence number at the LOS plant was assigned regardless of model or body type. By this we mean that Camaros and full-size passenger cars both incremented the same sequence counter. The unit counter was reset to 1 the next day as the day-of-the-month code letter incremented to the next letter. In the example, F103 would indicate approximately the sixth day of production for a given month and about the 103rd body on that sixth day of production.

NOR - (1967 only) NOR interior paint code

The NOR (Norwood) interior paint code, used only during 1967, is a single letter and is the same character as used on the Protect-o-Plate (POP). See the POP decoding section for other details on the Norwood interior paint code.

  Field c - body style code 12xx7 (See also this explanation of why the Fisher style and VIN prefix differed.)

The two digit year ("67," "68," or "69") was followed by a five-digit "ST" body style code, e.g. 12437. The first two digits of the style code are the model code ("12") and the last two digits are body code ("37" for coupe and "67" convertible).
While the Fisher style code is often confused with the first five digits of the VIN, the two codes are different because of the different meaning of the third digit. In 1967, the third digit of the style code was set to "4" for standard interior or "6" for custom interior (e.g. a style code for a 67 convertible with custom interior would be 12667). In 1968-69, the third digit was fixed at "4" for all models (L6 and V8) and had no meaning.

  Field d - assembly plant code

The next three letters represent the assembly plant ("NOR" for the Norwood, Ohio factory and "LOS" for the Los Angeles (Van Nuys), California factory. In mid-December 1968, the "LOS" was changed to "VN."
The digits that follow, up to six, represent the Fisher body number. Details on the body number can be found in the Body Numbering article. The body number is not the same as the VIN sequence. In 67-68, the body number was approximately sequential, increasing as more cars were built during the model year. In 69, the body number was assigned when the order was accepted, not when the body when built. Body numbers from cars that were built at the same time can vary significantly, depending on how quickly the order was fulfilled.

  Field e - interior trim code

The first three digits of the trim ("TR") code are a unique (for each year) interior color and type code that indicate the color and standard or custom interior.
1967 tags also have a hyphenated suffix that indicate seat and headrest type:
    Z - standard A50 Strato Bucket seats (no headrest)
    Y - RPO AS2 headrest added to the A50 bucket seats
    H - RPO AL4 Stato Bench seats (no headrest)
    T - RPO AS2 headrests added to the AL4 bench seats

  Field f - exterior paint code

The "PAINT" or "PNT" fields show the body paint color and the top color, including vinyl or convertible top, if so equipped. For cars without a vinyl or convertible top, the body paint color was stamped on the tag twice, e.g. E-E or 69-69.
Paint codes were alphabetic in 1967-68, and numeric in 1969. Vinyl and convertible top codes were numeric in 1967-68, and alphabetic in 1969. Two-tone paint was offered only with the 1969 models. Special paint cars were marked with special codes, as noted in the special paint section.

  Field g - body-related option codes (see the 1967 Fisher Option Codes and the 1969 Norwood X codes)

In 1967 this was a list of numbered option groups where each character represented a body-related option that required some action on the part of Fisher Body to alter the "baseline" configuration.
This information was eliminated in 1968, but in mid-year 1969, the Norwood Fisher Body plant began using a new body paint/trim coding scheme - the famous X codes and other codes including D80, Z10, and Z11.
1967 "fleet and special order" (F&SO) codes were also stamped in this area of the tag by both factories to indicate special vehicle order(s). The format was a dash, a 3-digit number, and a letter, e.g. -061A. Most special orders were for special paint.

Exterior Color Codes

Below are the CRG tables, with footnotes, for exterior paint and vinyl and convertible top colors, and the relationships between them. Related topics that are also covered below include:

• Special Paint Designation
• Window Sticker Paint Codes

Cowl tags and POP tags in 1967 and 1968 used a letter code for body paint and a numeric code for the vinyl/convertible top. Cowl tags changed in 1969 to use of a numeric code for the body paint (with two-tone paint now a Camaro option) and a letter code for the vinyl/convertible top color. For cars without a vinyl or convertible top, the body paint color was stamped on the tag twice, e.g. E-E or 69-69.

The 1969 colors are presented in the same row as the two-letter RPO suffix that was added to the 1969 window sticker. For example, 1969 Dover White, code "50", is shown in the Exterior Paints Table in row "C". This means that the cowl tag would have shown "50-50" and the window sticker, as shown in the Exterior Paint RPO Codes Table, would have had "5911CC DOVER WHITE" printed on it (where the initial "5" is the Chevrolet prefix indicating Camaro).

Non-standard paint color and striping color could be special ordered, and such cars were specially marked. See the Special Paint section for more details.

Stripe colors (white or black, with red added in 1969, and pace cars being a special exception) were selected based on body color. In 1967-68, there were three color combination exceptions where top color overrode that selection. In 1969, stripe color selection became more complicated as Chevy decided to make the stripe color vary depending on the top color. 1967-68 stripe colors are shown in the table below. The 1969 Stripe Color table shows the 1969 stripe color (W=White, B=Black, R=Red) as a function of top color and type; the legend for the top color codes are shown in the Convertible Top Colors and Vinyl Top Colors tables.

Stripe colors were painted as follows: White stripes were painted with Ermine White or Dover White, black stripes with a black that was different than Tuxedo Black, red stripes with Monza Red, and 69 pacer stripes with Hugger Orange. The various stripe designs and usage are shown in the Exterior section.

Table Footnotes:

1. 1969: Tuxedo Black coupes with Black interior and D90, DX1, or D96 stripe (not Z28) and with* or without a black vinyl top received a Red stripe. Some early production black with black interior cars received white stripes - it's not known when the production stripe color changed to red. (* Note: GM documentation incorrectly states that black cars with black vinyl tops would have a white stripe).
2. 1969: Cortez Silver and Dover White coupes with Red interior and D90, DX1, or D96 stripe (not Z28) and without vinyl top received a Red stripe.
3. 1969: The default stripe color for Burgundy was initially red. However, the "Camaro Striping Color Application Chart" dated 4/1/69 clarified that Burgundy Z28's and non-Z28's with either Parchment vinyl top or white convertible top received white stripes.
4. 1969: While the dealer literature reports that a black stripe is the default color with LeMans Blue, only white stripes have been observed in practice, except for special orders.
5. 1969: 79 Rallye Green was added as allowable color for the Midnight Green Vinyl Roof circa January 1969.

SPECIAL PAINT DESIGNATION

In 1968-69, either deletion of a stripe or use of a non-standard stripe color was also considered to be special paint.

In 68, if any of the four colors (A, E, H, T) that were deleted mid-year (see note in the Exterior Color table) were ordered in the latter part of the year, the cowl tag was coded as special paint on Norwood cars (although Los Angeles cars normally used the cancelled color code).

On the window sticker and on broadcast copy sheets, "1001AA" and "1001HA" have been observed as designating special paint cars. Note that all cars were painted, no Camaros were shipped from the assembly plant in primer.

Cowl Tag Coding

1967 special paint cars used the letter "O" instead of the normal color code. 1967 cowl tags also had a dash (-) or the F&SO code stamped on the lower part of the cowl tag. The format was a dash, a 3-digit number, and a letter. For example, some of 1967 Norwood-built Indy Pace Car replicas used the "-061A" F&SO code.

For early model year 1968, the designation for special paint cars changed to the letter "Z". However, the new mid-year colors were assigned codes and starting January 1968, the letter "Z" paint code was used to denote the new Camaro color called British Green, and simultaneously the notation of special order paint was changed to a dash "-". The "-" special paint code continued for the rest of the 1968 model year as well as for the entire 1969 model year. Due to changes and differences in how the factories marked the paint codes, the special paint formats are best illustrated in the examples in the Special Paint Table below.

(1) Note that black tops are shown in all the examples.
 
(2) It is unknown how or if a 1967 "stripe delete" car
    was marked. Stripe delete was considered "special 
    paint" in 1968-69.
 
(3) In 1967 only, a dash can follow the standard option 
    codes at the bottom of the cowl tag. This dash may 
    appear by itself or it may precede the Fleet & Special 
    Order (F&SO) code. This dash indicated that there 
    were special instructions (the F&SO paperwork) for the 
    vehicle. The dash and/or F&SO would also be on vehicles 
    ordered as part of a fleet.

1967 Cowl Tag - Fisher Body Codes

A table of the known 1967 Camaro Fisher Body option codes is below. Fisher factory documentation for these codes is not available. Nevertheless, a large number of the code meanings have been confirmed via a Fisher production form called the Uniform Option Identification Tag (UOIT) that was sometimes (fortunately for us) left in the car during build - often under the carpet or inside the headliner. The codes that have been confirmed via available UOITs are noted - and the exact wording of the UOIT description is shown in capital letters. The remaining codes have been decoded via statistical analysis and are therefore inferred. The CRG would appreciate a contact from anyone that has found an original UOIT form so that different versions (even of codes we already know) can be compared, and inferred codes determined exactly.

At the LOS factory, the 2M code was used for either the Powerglide or the TH400 automatic transmission, i.e. the 2Z code was not used at LOS. Early TH400 cars didn't have the 2M on the tag until mid-March.
At the NOR factory, the 2M code and the 2Z code only applied to automatic transmissions that were in combination with the D55 console (2G). Early cars with TH400's and consoles don't have 2Z notated on the tag until mid-April. Without a transmission designation (2B or 2L) on the cowl tag for NOR cars and without a console, the car could be either a 3-speed manual column-shift or an automatic column-shift.

The 4P code was not used at the start of production at either the Van Nuys plant or the Norwood plant.
Van Nuys started using the 4P code on the SS350 cars in September, but Norwood didn't start using the 4P code until October. Early Van Nuys SS350 cars and Norwood SS350 cars built before October will not have the 4P code to verify that they are SS's.
The 4P code can indicate either a SS350 or a L30/M20. Usage of the 4P code with the L30/M20 is believed to have started in the late December 1966 / January 1967 timeframe.

The very first 1967 Z28's and L78's were also coded 4P; the 4L and 4K codes were then used on the remainder of 1967 Z28 and L78 production.

The lack of a 4P, 4L, 4N, or 4K code indicates the car originally had a 327 (assuming the car had a V8, as indicated by the VIN). The only exception is the early SS350's noted above.

Fleet and Special Order (F&SO) codes (e.g. L181A and -061A) were also stamped in this area of the tag by both factories to indicate a special vehicle order. In most cases, these special orders were special paint instructions.

This tag decodes as having the following options:
756-H = (AL4) Strato Back Bench Seat -
             black standard interior
1E = (A01) Tinted All Glass
1X = (A31) Power Windows
1L = (A67) Fold-down rear seat
2E = (C60) Air Conditioner
2M = (M35) Powerglide Transmission
4F = (D33) Mirror Remote Control
5C = (AS1) Shoulder harness - regular

1969 Cowl Tag - X Codes

The Xnn codes were a mid-1969 model addition to the Fisher Body cowl tags of Norwood-built Camaros, starting with the 12B (second week of December) build week. (CRG has found 12B cars both with and without these codes. Our data for all cars in prior weeks is absent this code, and our data for all cars in weeks following contain this code.) These codes were an aid for Fisher body assembly workers to identify body trim and paint changes required for different Camaro models. The codes are divided into two groups: those with the Z21 style trim option and those without the Z21 style trim option.

The Z21 Style Trim group was part of the Z22 Rally Sport option, so RS cars are part of the group with the Z21 style trim option. Thus RS cars can only be X11, X22, or X33.
X11, X22, or X33 cars have to have style trim, but from the code you can't tell if the car also had RS.
X44, X55, X66, and X77 cars cannot have the Rally Sport (or style trim) option.

 X33  Z28                    X77  Z28 

 * COPO Camaros were an exception, as most COPOs 
   were built out of bodies coded with X11 or X44.
   Some early COPOs had X22 or X66-coded bodies.
   
 Additional 1969 Norwood Fisher codes that were 
 used instead of the X-codes include:
   Z10 - Indy Pace Car replica coupe
   Z11 - Indy Pace Car replica convertible

 Additional 1969 Norwood Fisher codes that could be
 combined with the X-codes include:
   D80 - signifies the car was equipped with D80 
         spoilers, but the code was not always used. 
    A  - signifies the car was equipped with power 
         windows, but the code was not always used.

1969 non-SS convertibles without style trim, built after Feb 69, did not have X44 stamped on the cowl tag. It is unknown why this occurred.

Note that X11 and X44 codes also included L26 230ci/130HP and L22 250ci/155HP 6-cylinder engine cars, as well as models equipped with the LF7 327ci/210HP, L14 307ci/200HP, L65 350ci/250HP, or LM1 350ci/255HP engines.

So, how many cars were coded X11?
Some quick math yields that 77% of 1969 Camaros were non-SS and non-Z28. After Dec 68, these cars would be coded X11 and X44. Multiplying the that percentage with the percentage of cars that had style trim or RS (58%) yields a little more than 44% of X-coded 69's were non-SS X11's. A similar calculation on the SS350 (9% of 69's) production quantity yield that less than half would be X55, the balance would be X11, about 5%. Adding these totals together shows the total of X11-coded cars to be approximately 50% of all 1969 X-codes. The corollary is that only about one in ten of X11-coded cars are actually SS350's.

X-code explanation

The following will help explain why the X-codes were arranged that way and their specific purpose. The need for this organization revolves around the elements of the Z21 Style Trim option in 1969, which included the following items:

• Bright vertical bars in taillamp lenses
• Bright driprail moldings (except convertible)
• Black body sill (except certain colors)
• Bright wheel opening moldings
• Wheel opening paint pinstripes (n/a with D90 stripe)
• Bright rear quarter simulated louver moldings
• Bright headlamp bezel face moldings

So what specific features did the X-codes imply; what did the codes mean to the workers on the Fisher assembly line? The X22, X33, X66, and X77 code differences are easily explained by paint differences (Z28 stripe and 396 tailpan), so it is the X11, X44, and X55 codes that require greater analysis. To further confuse matters, the non-Z21/Z22 1969 SS cars did incorporate a subset of Z21. To understand the differences between the X11, X44, and X55 codes, examine the comparative table below:

                                  Non-SS                  SS

 Bright headlamp bezel trim   no    yes    no      yes   no    yes

    Z21 = Style Trim
    Z22 = Rally Sport

As can be seen from the table above, the X11 code always includes the first four features: the use of black body sill paint and the use of the trim moldings (rear quarter louver, driprail, and wheel opening). The difference between X11 and X55 is that X55 does not apply the driprail and wheel opening moldings.

From this table, we can deduce that the wheel opening stripes, headlamp bezels, and taillamp lenses were not a factor in the X-codes. The table also show that the addition of Z22 (which eliminates the bright taillamp and headlamp trim, since the Rally Sport lamps are different) has the same effect on the X-codes as Z21.

Going back to the X22, X33, X66, and X77 codes, their meanings are now clear. X22 and X33 codes have the same meaning as the related X11 code, but with an added blacked-out tailpan for X22, and with an added Z28 stripe for X33. The X66 code has the same meaning as X55, but with a blacked-out tailpan. The X77 code has the same meaning as X44, but with a Z28 stripe. Including these meanings in a table covering most of the major trim features for all of the X-codes, and adding in the related Z10 & Z11 codes, we get the following result:

                              with Z21 or Z22               without Z21 or Z22

Protect-o-Plate Decode

The Protect-o-Plate (POP) is a small stamped metal plate that was provided with each vehicle by the factory as part of the warranty and service package. It was atttached to the vehicle's warranty booklet. When the vehicle was sold, the dealer added the customer's data name and address to the metal plate via Dymo-type stamped plastic adhesive labeling. Note that the data is stamped on the POP as a mirror image, so that the imprint from POP was correctly oriented.

The POP contains basic ID data about the powertrain components (engine and carburetor, transmission, and rear axle) as well as selected factory installed options, and the month of manufacture. 1967-68 POPs also showed the exterior colors from the cowl tag as well as the interior paint color.

POP data were stamped on a 8 row by 30 column grid at predefined coordinates. Instructions for stamping the POP data were contained in the assembly manual for each year, and decoding instructions were included in parts manuals and service manuals and bulletins. There are nine basic fields - illustrated in the POP transcription below and summarized field by field in the following list. For each data item, the row/column positions of the starting and ending cells on the plate are noted, with rows being labeled A thru H, and columns as 1 thru 30.

In the simulated 1968 POP (below left), each of the bold-faced monospace characters in the field of the plate is selectable and leads to a more detailed description of that field, which, in turn, often has a link to even more detail. The example describes a 1968 Camaro with a gold interior and British Green body with a white vinyl top. After the VIN is the code for a Carter carburetor. The engine is a L30 327ci/275HP for a manual transmission, the axle is a 3.07:1 ratio 12-bolt, the vehicle was assembled in January, and the transmission is a Saginaw 4-speed. The details of the specific component decodes can be found in the links to the Drivetrain Decoding page in the descriptions that follow.

The 1969 POP pictured (below right) decodes as a Norwood-built car that was assembled in March with a drivetrain that was built in late February. It had a Bay City carburetor, 307/200hp engine, Powerglide transmission, 2.73 10-bolt axle, and a radio (via the 3 option code under the axle code).

1969 Protect-o-Plate

The option field in the 68 POP example above decodes as follows. The first option position at C-15, the "3", indicates power steering (N40) and power brakes (J50). The second option position at C-16 was unused in 1968. The third position at C-17 indicates AM radio (U63) with rear speaker (U80). The fourth position at C-18 indicates F41 suspension with disc brakes (J52). The fifth position at C-19 indicates air conditioning (C60). And the option code in the sixth position at C-20 shows electric windows (A31).

The coordinates and details of each of the nine fields follow:

   One-character code that is also used on the 1967 Norwood Cowl Tag, and is described in detail in the Interior Colors section.

2. A-5 to A-6    Exterior Paint (1967-68 only)
   Two-character code that is also used on the Cowl Tag, and is described in detail in the Exterior Colors section. The first character describes the lower body color and the second character describes the upper body color. For 1967-68 the upper body color was always the same as the lower body unless a vinyl top was installed or the car was a convertible.

3. A-15 to A-27    Vehicle ID Number
   The 13-character code that is the same as is used on the vehicle VIN plate.

4. A-29    Carburetor Code
   One-character code that describes the source for the carburetor.

        B = Bay City (1 bbl/2 bbl)
        C = Carter (2nd source for Rochester)
        R = Rochester (2bbl/4bbl Quadra-Jet)
        H = Holley (4bbl)
        

5. B-1 to B-7    Engine Assembly/Application Code
   Seven-character code that begins with the engine factory code letter and is followed by the assembly date as a 2-digit month and a 2-digit day of month, then ends in a 2-letter application code. This entire code is the same code stamped on the front of the engine block.

6. B-15 to B-21    Rear Axle Assembly Code
   Seven-character code that begins with the 2-letter axle factory application code, is followed by the assembly date as a 2-digit month and a 2-digit day of month, and ends in a 1-letter factory code. This entire code is the same code stamped on the axle, except for the absence on the POP of any shift suffix or positraction code. Note that when faced with an axle of uncertain vintage, the year of manufacture must be derived from the axle center section calendar year casting date.

7. B-29    Vehicle Build Month
   One-character code from the following table.

              Aug Sep Oct Nov Dec Jan Feb Mar Apr May Jun Jul
         1967  V   L   R   K   Z   S   P   W   N   Y   T   X
         1968  8   9   O   N   D   1   2   3   4   5   6   7
         1969  8   9   O   N   D   1   2   3   4   5   6   7
    late 1969  8   9   O   N
        

8. C-1 to C-5    Transmission Assembly Code
   This five-character (typically) code begins with the transmission factory code letter and is followed by the last digit of the model year (not the calendar year) and the assembly date as a 1-character month and a 2-digit day of month. This code is the same code stamped on the transmission (on the trans pad, flange, pan, and/or tag). The shift code is stamped on some transmission models and often is included on the POP. The Muncie model (ratio) suffix, which started in late October 1968, was never stamped on the POP.
   The TH400 uses a different code format - see the tranmission decode page.

9. C-15 to C-21    POP Option Codes
   The first digit of the POP option codes starts immediately under the first digit of the axle code. The position of the digits matters and the interpretation also changes as a function of model year. Note that some 1968 codes were used for vehicles built late in the 1967 model year.

   In the table below, the locations are noted as positions C15 through C21. The meaning of the RPO codes (such as J50 and J63) listed are available in the downloadable option spreadsheet. Also, see the further explanatory notes below the table.

10. C-29    Chevrolet Symbol - vertically oriented

Again, the option field (i.e. 3 4511) under the axle code in the 68 POP example shown at the top of this section translates as follows:
The first option position at C-15, the "3", indicates power steering (N40) and power brakes (J50). The second option position at C-16 was unused in 1968. The third position at C-17 indicates AM radio (U63) with rear speaker (U80). The fourth position at C-18 indicates F41 suspension with disc brakes (J52). The fifth position at C-19 indicates air conditioning (C60). And the option code in the sixth position at C-20 shows electric windows (A31).

The option field in the 69 POP example shown above indicates the car had a radio (location C-17, the 3rd character over under the axle code).

Options were tracked more fully in 1967 and 1968 than in 1969. In 1967-68, codes were generally selected such that option combinations, in keeping with efficient computer coding practices of the day, could be obtained by adding together the codes of each single option. Several options and their permutations could be recorded with a single digit. For example, in position C-18 for 1968, J52=3 and F41=2, so the combination of J52/F41 was assigned the value of 2+3=5. From this practice we can infer the existence of codes that do not actually appear in the Chevrolet Service News Bulletins. For example, in earlier CRG research, the 1967 code for B93 Door Edge Guards was inferred to be 4 in position C-20, since A31 was known to be 1 and the A31/B93 combination was known to be 5. The inferred value for B93 without A31 was later confirmed by other GM records, which also confirmed the previously inferred A67 code in field C-20 for 1967.

  There are a few items of note about position d (Brake / Suspension) in the option field:

• While the F40 heavy-duty suspension is not listed as a 1968 Camaro RPO in the US, it was supposedly available to Canadians. While CRG has not yet seen a 68 Camaro with this RPO (F40 was an available RPO in 1969), it is included in the POP option codes for completeness.

• With regard to RPO J56 in position C-18, the "Heavy Duty Brake" option, GM has noted this as a 1968 POP code, despite J56 being a 1967-only option. But CRG believes that values 6, 7, and 8 in 1968 refer to the Corvette J56 four-wheel disc (4WD) brake setup. The 4WD setup is referred to in the 68 Camaro Assembly Manual initially as J56 but was changed to JL8 circa Feb/Mar 68. The four-wheel disc brake system was never installed in a 68 Camaro by the factory, and we have never seen the 6, 7, and 8 codes on a POP. This brake system was available for the 68 Camaro only as an over-the-counter Service Package. These codes appear to have been included for 1968 in preparation for a proposed option release that never occurred. The 4WD Service Package was modified and finally made available in 1969 as a true factory option, RPO JL8.

1969 Warranty Protect-o-Plate

    Warranty and Canadian Protect-o-plates

Canadian-sold vehicles were provided with unique Canadian warranty booklets. 1967 Canadian vehicles have a plastic protect-o-plate that is only stamped with minimal information like the VIN, the buyer's name, and the zone and dealer's number.  

GM Date Code Formats

For cast-in date codes on GM-produced iron and aluminum castings (engine blocks, heads, intakes, water pumps, etc.), the letter "I" was used for September, and the last month of the calendar year (December) was the letter "L". For stamped-in date codes on GM-produced components (alternators, distributors, starters, etc.), the letter "I" was not used - "I" was skipped, and "J" became September, with December being "M".

(See the Casting codes article for more information on casting dates and codes.)

To summarize: For GM-produced parts, the month code for calendar year dates that are cast into parts runs from "A" through "L" (including the letter "I"), while the month code for calendar year dates that are stamped onto parts runs from "A" through "M" (skipping the letter "I").

 Stamped Date  A   B   C   D   E   F   G   H   J   K   L   M

A common stamped date code format is (year)(month)(day). 8C26 would decode as 8=1968, C=March, and 26=26th day.

A common cast date code format is (month)(day)(year). B129 would decode as B=February, 12=12th day, 9=1969.

"M"-Coded Blocks
There is one exception to this convention that has been observed: some blocks have been seen with "M" cast codes. Research by the Saginaw Metal Casting Operations of GM Powertrain Division has found that these "M" codes are not date codes, but actually a foundry code used to indentify parts that were made to evaluate a casting process change. After evaluating the parts, the blocks would either be destroyed or released into production. There is no way to determine the date an "M"-coded block was poured.
