71 Charger. There are two bumper alignment brackets that bolt into the front quarters and the other end is supposed to grab a welded bolt of some sort. On the passenger side the welded thing on the actual bumper inside is gone so the bracket has nothing to grab. Is the bumper material hard to weld? Not sure what kind of metal it is. Any other suggestions? I was even thinking of drilling a hole on the underside of the bumper and putting a bolt in there to grab.
