So my trunk door is cracked and I have a new one to replace it, but I'll be damned if I can't get it apart. I've got the trunk off the bike, and there are 2 screws oneither side of it that the door pivots on that I have to remove, but the screws just turn and turn and turn. On the inside I can see a rubber grommet, and a metal washer, but no nut on the screw. Am I missing something totally obvious here?
