Hey thanks to all the guys who have helped out with my car, but now i have anothewr question. I have a 1972 chevelle and it has the fac. rearend which is a 10 bolt (don't know the gears), but i'm looking for a 12 bolt rearend which i could put some nice gears and make it posi. I was just wondering if anyone could tell me which cars and years i could use a rearend from. And if yall have any gear suggestions i would gadly apperciate the advice. Thanks guys

I would think that any big block Chevelle from that era would have a 12 bolt that would work. Probably the best compromise between power and economy would be a 3.73 gear.

go to richmondgears.com and they got a calculator there you can use to determine what gears will work with what rpm you want.

oh and as far as parts go to randysringandpinion if they dont have well just say you probably wont need it.

hey guys thanks for all the suggestions and ideas

If you can find a 12 bolt out of a 66 or 67 , they are 1 inch narrower but will bolt right in. You can get more tire and wheel under it, I did this with my 70 with a 406=4 speed and it worked well.
