[Fot] TR frame square, straightness?

[davehogye]

Hello all, 
Does anyone know the tolerable limits to frame measurements for TRs. I'm about to put my TR3 body back on the frame and things are reading a little out. I have a 3/8" difference from front axles to back, and on the short side, the right, it's about 3/8" up on the front corner. The car did have a couple badly bent wheels on it when I bought it, but it had no evidence of being in any nasty fender benders and all of the body panels were original. It doesn't seem like a real problem to me, but now would be the time to tweek it a bit and I do have access to a frame machine. 


I'd appreciate any comments, 
Dave H.
