Advice Pleas on rear end.

What rear end is currently in the car? I'd suspect a 7 & 1/4 SBP. Worth rebuilding? Up to you but others likely to say no. I'd probably be looking for an A Body 8.25 (LBP) or an A Body 8.75 (most likely SBP) or 65-70 B Body 8.25 (LBP) and use different offset wheels. I'm personally going to use an 8.75 in my 3 early A's.
