Agreed with City Racer for wx stripping. Top notch stuff. He is rumored to be working on the stripping for 1974 styled doors which are NLA, as well. But I believe his product mirrors factory thickness. If you feel you need something thicker than OEM, check your door hinges. If the bushings are gone, there is a Mud member who sells new brass ones. New bushings will remove slop. Also, if you like to remove your doors, there is another member who sells a modified style hinge that facilitates that. Either might help. If the slop is in the latches, new OEM strikers are still available for some years.
