I have my truck down to the bare frame and I am getting ready to blast it ,but the frame under the rear spring perches is bent from years of heavy hauling .It probaly wouldnt bother a lot of people but it does me.My question is can I go ahead and cut the rivets from the spring perches and heat the frame up and correct it or should I avoid the heat all together?And is it okay to bolt the spring perches back to the frame where the rivets were?
Thanks for your help
