I am wondering what is the best way to straighten my frames rails. I have a 55 shortbed frame that I believe somebody previously to me has picked it up on the right side of the top of the frame rail bent the top rail upward. I was reading the shop manual and says not use heat to straighten the rails. Anybody done anything like this yet? If so let me know the best way to straighten these out, and how critical it is to be perfect. Thanks Brad.
