Thanks, it may be a aftermarket universal/ fit all, for all I know. I know it looks like a lot of the ones from the 60-70s cars and I got it in the late 70s/early 1980. I'll keep searching, thanks though , least I know it is not Mustang/Ford now.

I have some NOS mirrors that look a lot like those on a 69 Mach 1. Part # on inside of base is 60655-401. I've had these NOS mirrors for 25+ years & never was sure what they were for. Can anybody tell me? Are they even Ford mirrors?
