The Amazon sourced mirror is clamped by two thumbscrews. The other is held
by a large self adhesive pad. I wouldn't put either of them high up on a screen
due to a) Vibration (as Dave said ) and b) The screen is not designed to be spot
loaded and it may well break/crack at highway speeds.
I am working on these right now. May or may not work for different people, but I only have about $45 in the mirrors and stuff from the hardware. i have a bout an hour in modifications. Don't have the finished product yet and need to field test.
It is a PDF format. Therichardsolodrivingmirror.com Now if you go to the website Richardsolo.com there is all kinds of stuff the site sells but I cannot find the Mirror. Even has a model number: Cycle Model RS511 (on the PDF file). I think it a good idea because of the hight of the mirror keeps your eyes up on the road more. Good luck.
