Re: 12-Bolt Axle numbers stamping inquiry
99% certain the "C" designation did not come along until Aug of 69. However, if you can get the casting date, that will probably solve the question of which year.
Remember, in Aug of 69 Chevy was making 70 model Novas and still making 69 Camaros. That's why the late Camaros are often referred to as 69 1/2 models. Starting first week of Aug. 69, they had to comply with federal standards for 70 models even though titled as 69's. That's why most of the 08A and later Camaros had the mylar VIN sticker in the driver's door jamb. My car was evidently one of the last NOT to get the sticker. I know the car that was 86 cars later did get one. Both cars are 08A.
Anyway, the Novas and Camaros still received the same rear axle assemblies up until sometime in November 69. I had an October built DZ motor. I think CRG has some figures on the apprximate date for the last 69 to roll off the line. At any rate, there is no doubt that 69's were still being assembled in November, so that rear could have gone in a very late 69 COPO.
Try and get casting date and casting number. I am especially interested in the casting number for personal reasons.
Sorry this is so long.
