So i have a 96 f150 ext cab and i am doing a frame off resto since i live in ohio and we use salt which has done a number to the fame. so i am going to clean the frame, coat it in bedliner and then rebuild. the problem is is that i can't remove the bolts that attach to the cab or the radiator supports or anything. so yeah the question is, How do you remove the bolts? ALSO on that same note i want to replace the bushings since as you can imagine they are shot. is there a easy way to remove the cab bushings also???
