GM 12 Bolt Gears
 

Anyone ever pull out or hear of a set of gears and posi removed from a 69 camaro 12 bolt and only the pinion is stamped GM not the ring. I have a set of 373 just removed from a 69 rearend like that. The pinion has 2-69 and part number 3862534 but nothing stamped on the ring. There is some white ink stamped markings on it that's all. I haven't taken it off the Eaton 3 series posi yet is it possible to be stamped on that side. Larry.

I've had GM gears that had the ring gear stamped on the mating surface. The numbers could not be seen until the gear was removed.

Good call "big gear head" I pulled the ring off and sure enough its stamped. I had thought of it but only got that far. Thanks for the suggestion. Larry
