This is too funny... I got in touch with that company a couple days ago for a replacement mirror for my '65 Barracuda. I needed a 4 3/16" diameter mirror to fit my remote mirror.
I ended up talking to the owner for quite a while on the phone.... Quite a interesting person and a really nice guy to deal with. He was talking about different ways of promoting etc. and reaching out to enthusiasts. I enjoyed speaking with him.
Got my mirror today and it's a good piece. About twice as thick as the other replacements I looked at and I'm pretty happy.
