3.64, 8.2 gear set or pinion

We need a 3.64 gear set which was stock in a non AC 70 455 car, auto or manual trans. We have a crack in the pinion gear of the original set.

 

Jim, If you can't find one I'll check with a friend about repairing yours. There is an old fellow in the area who repairs all kinds of parts. Believe it or not my ring gear is missing 2 teeth. I never knew they were gone untill I drained the rear and I'm telling you I pounded that rear. So I am putting in a 12 Bolt rear. I cannot put the original drive line back in my car because I drive my cars very hard.

 

I would appreciate it. Would it help to send you or him a pic to see if he might tackle it.

 

Jim, If you want email the pictures to me at torquex@comcast.net, I'll help you in any way I can.

 

Pics were sent.

Thanks

In the meantime if anyone has this pinion (GM # 1231469 on the backside ) I'm interested. The ratio is 11-40-GM on the same side as the part number.
