Resurrecting this old thread due to an ongoing issue I have had. Ever since getting my current rig about 4 years ago, I have dealt with the review mirror falling off a few times. When I first got it, the mirror was glued to the windshield and the glue gave way and it fell off in only a few weeks. I got some of the glue at the local auto parts store and reattached it. After about a year, it fell off again. I got a different brand/type of glue, made for mirror mounting or course, and after about 6 months, it fell off again. I finally resorted to some Gorilla gel super glue and that held for about a year. Well, it fell off again yesterday. So I finally decided I'm tired of gluing it to the windshield and wanted to mount it to the windshield frame instead. Now I do have a roll bar or windshield hoop that sits right behind the windshield frame, but I changed my mirror a while back for one from the scrap yard that has map lights in it and I ran the wiring inside the windshield frame to power it. (Here's a link to that post:
Mirror with map lights) I do fold the windshield down from time to time and didn't want the mirror mounted to the roll bar and the wiring inside the windshield frame, because I would have to unplug the wiring connector every time I wanted to fold down the windshield. So the mirror needs to stay connected to the windshield frame where the wiring is and go with the windshield when it gets folded down.
So the plan was to use the existing mounting "button" (the metal piece you normally glue to the glass) and mount that to the underside of the windshield frame with some screws and then put the mirror onto the button like normal. Here's the mirror and the metal piece you glue to the glass to mount it. Notice the two buttons on the bottom of the mirror itself that are used to turn on the map lights. And here also is the mounting location, next to where the wiring comes out of the windshield frame (centered just under the frame where the footman loop is on the vertical "face" of the frame). Of course the footman loop is used for the strap on the safari top.
So I drilled two holes into the metal mounting piece, and countersunk them so the screw heads would be flush, allowing the mirror to slide onto the mount once in place. I wanted two holes rather than just one so that it would never swivel or move while adjusting the mirror later. I then also drilled two holes into the underside of the windshield frame to mount it. So here you can see the piece mounted to the underside of the windshield frame right next to the wiring that comes out to power the mirror. You can also the footman loop with my safari top tensioning strap as well as the roll bar windshield hoop section.
Next was to simply mount the mirror onto the metal mount like normal, using the set screw in the mirror to tighten it all up. All I had to do was rotate the mount on the mirror 180 degrees to put it on the mount in this new location/orientation as opposed to how it mounted before when glued to the glass. Then plug the wires back in and presto - a solidly mounted mirror that no longer relies on glue to keep it on the glass. And yes, I can still fold down the windshield with the mirror attached like this as it just clears the roll bar section enough to do so.
