After i put everything together, something got screwed up with the pinion. So instead of trying to fix it, because it was just an old 8.2 with a half rusty ring gear, i'm searching for something else. A local yard has 3 A-body rears, a '72 Monte Carlo, '70 ElCamino, & '70 Olds. I have a couple questions,

1. I know the ElCo rear should be a direct swap, but what about the others? Whats different on them?
2. Would i be able to use my Superior forged axles and Richmond LockRight in say, the Monte rear?
3. What are the chances the Monte rear is an 8.5?

Exactly, my guess is that the Monte rear is 8.5, and the Olds is 8.2 BOP. I just want a direct swap into my car and would rather not have to spend any more on parts. If the Monte rear is 8.5 and would bolt right in, would i have to upgrade the axles? Main reason i did on the 8.2 was because of that, its an 8.2. lol
Ok i just got back. There were 3 rears, the 72 MC rear was 8.2 with 2.73 gears, a 70 ElCamino rear that was locked, and a 69 Chevelle rear that had the pinion half busted off.

So he tells me he'll sell me his 1 season old dirt track rear that he's been sitting on for a while. Its a 10 bolt 8.2 with new 3.73s and a minispool he'll sell me for $200. I think i'm going to take it just because i already have brand new axles and Lock Right to strengthen it up. I just hate going with another 8.2.

Also I'm going to need a conversion u joint. My old rear had 4 bolts that connected the DS, U-joint to the pinion yoke. This yoke just has 4 holes without threads. Which conversion u joint do i need?
