Frame repair

[jnobles06]

So i a buying a known wrecked 95 cobra for a donor car to build a nasty 5.0 based new edge. The car is in mechanically great shape, but it keeps chewing up rear ends with in a few thousand miles of it being rebuilt. So the owner wants to get rid of it cheap. I was now thinking about getting a shop to fix the frame and just selling the new edge to help fund the new drivertrain going into it. I want to get it done right so; what's the best place?

Edit.
The reason i know its been wrecked it because i can see its been on a frame machine before i am thinking it will take minmal work to get it straight like it should then i am going to slap some full length sub frame connectors on it.

I also thought about getting come adjustsble lower control arms and just using those to square up the rear end, but thought that might screw with the angle yoke goining in to the transmission or something.

Sounds like a bent housing or lack of proper set more than anything else.

I would start with a simple wheel base measurement first .

Well i plan on doing that, but i am the one who modded the hell out of this car and as soon as i put aftermarket control arms on it, and had the rear-end rebuilt the first time with all 31 spline stuff; it started going through rear ends every few thousand miles. Plus i noticed when i was putting long tubes on it; the h-pipe that matched the headers was about 1 inch off, and i had to take it to an exhaust shop to have them bend it so it would line up.
