67 mono springs use decals?

[Mike S]

 Did 67 mono springs use P/N decals or was the 'color code stripe' mentioned in 67 AIM UPC 4 B1 used as an identifier instead?
My 67 LOS survivor has the F41 suspension as evident by the front coil spring tag P/N 3912532 YJ I removed (looking for a place to duplicate it).
On the same car is the paint code stripe that shows a definite yellow color as shown in the attached image in addition to the smoke gray spring color.
If I cross referenced my numbers right, the mono spring should be 3925817 BY (12437, L35 & F41).
To date I have found no info for the 'color code stripe' summary so maybe this one if a first for CRG?
My thinking is a paint strip was used in 67 and then a decal in 68 and up.

Thank you,
Mike

About 10 years ago Mike Rossi and I were doing a lot of research on whether or not spring tags were ever used in 67 on the rear springs. We did find that the LOS plant did not use any tags on the springs in 67 and on some early 68's with mono-leaf rear springs except for two springs coded BA and BX. I do not remember if we ever found a 67 LOS car with tags for the other spring codes, and/or any 67 NOR car with the paint stripe on the springs. However, the color chart can be found in original P&A manuals for most of the springs. Per my information the paint stripe on your spring should be purple, not yellow. The yellow stripe was found on the 3909940 spring which was the standard rear spring for the L35 & L78 in 1967. I am not sure why you have F41 springs for the front, and non-F41 springs for the rear.....................RatPack....................

Here is a picture from an October 66 built LOS RS/SS 350 showing a coral paint stripe.......................

My 07B Mountain Green '67 Z-28 built at the LOS plant had spring tags on it, not the paint stripe on the front of the spring. That was an untouched car I bought from the original owner.

 That's is interesting there is a mixture of springs, RP.
My guess on that is one of two things happened:
1- The customer didn't order F41 and standard YG coil springs weren't available so the YJ was used to keep the line moving (shortage in customers favor)
2- The customer ordered F41 but the rear BY springs weren't available and BH were used to keep the line moving (shortage in Chevy's favor)
  Or, there is a third possibility in that the spring chart revised date of 3-3-67 shows a change in usage but the assembly line didn't incorporate it just yet in their process?
Maybe a fourth....I am going to study the stripe closer and see if it is coral and just the yellow hue is caused by the rust. What usage is the coral for?

Thanks for the feedback.

Jon, now that you mention it, I think Mike had mentioned that he found some late build LOS cars that had spring tags, your Z may have been one of them. Do you have any pictures showing the tags? I have a set of original Z springs here and I cannot find traces of a paint stripe on them either....maybe had the tags too?............

Mike, I just dug out my 67 AIM where I had originally started the research on this back in 1995/6 when I worked for Year One. Here is what I have noted from back then. One note is that the spring chart is confusing in the 67 AIM as it has a typo for the BX code spring which should be 3925816 not 5925816, and that spring is the coral colored one: coupes w/L30 or L48. I also mistated that the two I didn't have stripe colors for were BA & BX, but it was BA & BB.

These are my notes from 1995 or so:

3925815 became 3912527 : first is white stripe and supersede had a yellow stripe, 1220 lb spring
3925816 became 3901395 : coral stripe,  1310 lb spring
3925817 became 3901397 : purple stripe, 1370 lb. spring
 
Now at one time all 6 springs were available at the same time, but they didn't always correlate to the 67 AIM when compared to the ones shown in the Feb 69 P&A 34 manual listed below:
 
3928515 - 67 Camaro coupe, 250 (ex spc rr spring) white stripe
3912527 - 67 Camaro 6cyl. yellow stripe
 
3925816 - ***No 67 applications shown
                   68 Camaro spt.cpe (327) exc. spec perf susp, 4spd)
                   69 Camaro
3901395 - 67 Camaro spt.cpe(230 & 327) (exc. spec perf susp) coral stripe
 
3925817 - *** No 67 applications shown
                   68 Camaro spt cpe w/spec perf suspension (exc. 350 & 396)
                   *** This spring was disco'd in 2/74 per my notes from Mike @ Eaton.
3901397 - 67 Camaro spt cpe w/spec perf. susp. (exc 350)
                   67 Camaro spt cpe (302, 350, 396) purple stripe

Confused? I am!!!...................RatPack.....................

Here is a photo of it.

Jon, what's the code? According to the AIM it should be "BY".

Mike, what's the build date of your 67 LOS L35?

If you look in the AIM it shows note 14 "Spring chart revised" on 3-3-67. There's a very good possibility that early 67's got a color code while later 67's got tags.

Ed

[Jon Mello]

It is the proper BY code although I realize that photo doesn't show it well.

[rat pack]

Jon thank you for posting the picture!

Ed, Mike's car is an 04B so that is after the chart revision. The AIM doesn't state what was revised so it could have been the addition/subraction of spring applications, the removal of the paint stripe colors, and/or the addition of the 2-letter codes..... Really no way of telling what it was......RatPack...............

[bertfam]

Yep. Just grasping at straws Troy!

Ed

[rat pack]

Ed, you are right!!! Just need to keep documenting original cars!!!     ....................RatPack.........

[Mike S]

 Thanks all for the informative feedback.
And RP, I did appreciate the posting you have done for the research on the spring colors. The chart in the AIM is confusing for sure.
When I restore that car I'll keep what was there despite the differences in the spring application codes (YJ sticker in front and standard application paint in rear).

Mike

04B- paint stripe no tag
06B- no paint stripe or tag
07B- tag no paint stripe

[Mike S]

MO,

  Which plant for those cars?

Thanks,
Mike

[MO]

Mike,

Those are the cars discussed so far in this thread...all LOS. I was just trying to tally what was on the board so far. Hopefully others will add input for research.
