Box frame??

[moggey01]

I put my frame on a chassis jig. You would be surprised at how screwed up a frame can get from years of driving and abuse. Mine is boxed and has upper and lower braces to the trailing arm crossmember. Its kind of a double"X" that extends towards the front of the cab into the boxed part of the frame. It will have a full cage eventually when I get to that point. I hope this helps .
