Here is a pic of the rear axle code of my 69 Camaro. This is axle and the date codes match up. My car is a 69 Camaro Pace Car with numbers matching drivetrain with a Powerglide and a 10-bolt rear. My rear axle is a posi unit and has a 3:08 ratio. The PG code shows as being a non posi rear so I am inclined to think that the posi may have been dealer installed. I purchased the car from the original owner who claims she did not add the posi to the car and that it had it when she bought it new. Any ideas on what looks like it could be a partial stamping near the axle code? Is this even a stamping at all?
