I know this was answered in the old forum but alas it is gone. I have started to experience the dreaded Connie mirror droop and I know I once saw instructions on how to adjust the bolt by making a small slit in the mirror boot. Could someone kindly post these instructions again? Thanks!
I had the bottoms of my mirrors split, but if the nut comes all the way off the bottom of the bolt, it's very tough to get it restarted through the little slit. I wound up cutting the rubber off the whole back of the mirror to get the bolt replaced.
I also switched the bolt for a metric hex bolt, flipped from stock, so the head is on the bottom and the nut is on top. This lets me use a 90 degree hex on the bottom, clearing the faring, and a socket on top without clearing issues. I'm happy with it this way, but it's uglier.
