Getting close to finishing my "68" and the last thing I thought I would be pulling my hair out over is the driver side sport mirror:thud: The rubber inserts inside the door panel are good and the bracket mounts firmly to the door. The problem I'm running into is when I slide the mirror over the bracket and install the base mounting screw into the bottom of the mirror, it will not tighten down the mirror. I run the screw in until its tight but the mirror sits on the bracket really loose, the mirror isn't tightening on the bracket . What am I missing?!?!
