going to start installing a body lift tonight and got all the nuts off the but can't get any bolts to come out, just lift up through frame mount and the back most bolt won't even do that but a half inch up. Looks like the back 2 bolts are tack welded to the body too. Any tips? I am to the point of griding off head then airhammer down but figured would see if there is any other ways people have done it. thanks.
