I can't remember for sure but I think it was a Kmart in the automotive section that sold a thin plexiglass sheet that you could cut to size and stick to the mirror. It was mirrored on one side and looked easy to cut and install. Also cheap. I am pretty sure it was Kmart but it might have been an auto parts store. Anyway it would avoid the work of removing the whole assembly. and you could diy. Good luck. S.
