Hey guys

I have a 34 chevy 3 /w, I just pulled the body of today and started getting the frame ready to go to the media blaster.
The frame is in good shape and it doesn`t look like its been in any wrecks but when I started measuring the frame to make sure it was straight and square I found that it was off by a 1/4 in. when measured from corner to opposite rear corner (basicaly the x pattern). I was just wondering if you guys think this is within tolerance for a frame this age or should I try to get it dead on square?
Thanks in advance
