Rear view mirror frustration.

[TheJDMan]

My inside rear view mirror has been a problem for over 40 years now. The design of the original Camaro mount relies on the tension of a single screw to hold the mirror head to the mount arm. I have tried all manor of ways to tighten the screw sufficiently to hold the mirror head in place but it inevitably slips and the mirror falls out of adjustment. This is not a new problem, I had this same issue with this same mirror back in the 70's I just never did anything about it. Now that I'm driving the car on a regular basis it has become a pain in the a** and it's time I take care of the problem once and for all. I'm looking for a permanent fix or replacement mirror assembly that will stay adjusted. Any recommendations?
