Wondering for opinions on things people have already tried. I am making a rear bumper for my XJ, and wondering if it is strong enought to attach it to the spots on the back of the unibody that are stock, for adding a 2" hitch spot for a pull spot, or would it be better just put a 2" hitch to the chasis? I just dont know the strength on the back end for the stock bolts on the back.
