Looking to build a 4x4 pup on a 1980 Bronco frame. Besides stretching the frame and rearranging the body mounts, do any of you fine folks see any forseen problems in this conversion. Would the unibody design give any trouble, like cracking or such.I realize there were factory model 4x4's, but I don't know enough about this era truck to see any problems. Reading your responses on the issues gives me faith in your opinions. Now that I've buttered you up... What do you'se think?
