I know this is an old thread, but my question pertains to tying an exo cage into the body of the XJ. Is it a good idea if I have rear quarter panel armor with a tree bar, to tie that into the cage or would that just cause damage to my quarter panel the first time I took a hit? would welding the cage to the gutters and pillars themselves do any good or should I just tie the cage into the bumpers, sliders, and unibody?
