On my 68, on the fuel door there were four rubber bumpers. Two very small ones on the bottom that kept the license plate from rattling and two at the top that kept the door from hitting the body. The ones at the top were screwed into the door. The ones at the bottom were just pushed through. I have looked at WCCC, AutoKrafters, Johns Classic Cougars, NPD and Mustangs unlimited to no success. Anyone know where these bumpers could be found? Especially the ones that screw on?
