Have 34 PU doors with stress cracks around the rivets of the lower hinge. Can possibly be welded. Other and possible better option is to remove the hinge, cut out and replace cracked metal and reinstall hinge. My question is, lower hinge is riveted on, so how big of mess/job is it to remove and then try to rerivet the hinge. Has anyone done this? Any tips or information would be greatly appreciated. Thanks in advance of all.
