Restoration / Re: Correct '69 L-78 front springs?

« on: September 17, 2007, 04:14:47 PM »

G31 and F41 were mutually exclusive, ie you can't have both on the same car.  G31 was special multileaf rear springs, and only 556 cars came equipped with them in 69.  F41 was special purpose front and rear springs and was only availble on non SS and Non Z28 camaros (either coupe or convertible), and came on 5929 Camaros in 69.  The F40 heavy duty suspension was only available on 6 cylinder coupes or convertibles.  I dont think any cars are recorded as having the F40 suspension.

I guess you could have G31 rear springs on a 69 SS, but they would be used with the standard (for the weigh options) front spring.  And since the G31 spring package came with the V32 rear bumperettes I would think that the ride height would be lowered if you had G31 on the car.

My PDF file lost a page somehow it dropped the Z28 and BB page.  Heres all three pages of the spring chart.  If your front end hass an additional 288 pounds added to it you should have HA springs, not YO.  YO is for a small block coupe (307 or 327) with that much weight.

Heres the GM spring selection charts for the 69 Camaros.  The list shows you the two letter spring code that corresponds to the tag that was on the springs.  There is another pair of charts that turns the letter code into the GM Service part number.

Except for the 4 leaf rear spring on Z28's (which could be used on other cars with the righ combination of options) there is really no such thing as a big block L78 or L35 or L48 spring.  In 69 springs were selected by a computer based on the vehicle type (coupe or convertible), engine type (L6 or V8) and the options added to the car.  This was due to the federal bumper height requirements and GM's need to keep the bumper height within a fairly tight band.  You can get a GM part number for the front and rear springs by adding up your options, but I don't know of anyone who has correlated them 1 for 1 to the moog springs that most of the aftermarket places sell.  Eaton can probably do it though.

Because production was supposed to end around the end of July and the dealers weren't taking as many orders.

If the M20 in the trunk has the cars VIN stamped on it, the rear end is a 12 bolt  BU coded axle with 4 leaf springs, power font disc brakes  and there is a single fuel line under the car then chances are its a Z28.

General Discussion / Re: Factory AC upgrade from R-12 to R-134a?

« on: August 13, 2007, 04:16:49 PM »

No, operating pressures are roughly the same between R12 and R134 and is controlled by the thermostatic valve, the POA valve and the ambient temperature outside.  R134 would like to see about 29 psi on the low pressure side to give you the same vapor pressure that R12 will give you at 34 psi.  Remember your POA controls the low pressure setpoint, so it will try to maintain around 34 psi in the evaporator which will prevent the R134 from getting as cold as the R12.  In either event the difference in operating pressures between the two is insignificant.

Originality / Re: 69 Camaro X codes, did they make SS's without them in june?

« on: August 12, 2007, 12:25:12 PM »

The TH400 codes are on a tag about 2" square riveted to the transmission on the passenger side.  Should start with the letter a C followed by another letter then 4 or 5 digits.
