frame questions

[JohnSPledg]

I would like to know if there is a difference in the frame from the rear cross member back between trucks and k5's, both 2wd and 4wd. I buckled the frame a few inches before the rear crossmember and it looks like it will be easier to patch the frame than to straighten it.
