[KR500]

Before attempting a job like this confirm what diameter hinge pin you are dealing with. There are 9/32 pins for the slant windshield and I believe '31 Cabriolet and Victoria. Also there are replacement oversize pins for the 1/4 inch pins. The 5 inch mirrors are supplied with 1/4 bolt pins and are somewhat loose in the doors. I mounted those 5 inch mirrors on a members slant and turned up 9/32 diameter pins tapped at each end to 8-32 thread. Pins were sized exact length of door hinge plus .010. Threaded into hinge pins 8-32 set screw and then placed short 1/4 -20 short studs down into mirror ends and threaded on acorn nuts supplied with mirror.
