Just purchased a Trenz flamed billet mirror from Moss (the one with the flames that stick up at the top, $129) & I was trying to install it this morning.
The 2 piece mounting bracket slid right down over the existing bracket on the windshield without any problem. However, when I tighten the mounting screw it did nothing. The bracket slides right back off.
Has anyone installed one of these mirrors? What do I need to do? Does the top of the 2 piece mounting bracket need to be glued to the existing bracket on the windshield first? If so, what kind of glue should I use? If I did that, then I think it would mount ok. But I didn't want to glue anything before I got some advice.
I tried calling Moss but they didn't know what to do. They said call back on Monday. I also tried called Trenz, but they're closed too.

Thanks, John
