That's an absolutely great template! I hope you didn't do that just for me? I've also seen the clips in Rick's catalogue but there is nothing special about triple chrome plating. It has to be done that way on steel parts (copper for the nickle to stick to, nickle for corrosion protection, chome for appearance and durability).
I will look up the ebay guy. Fortunately, the '67 convertible sunvisors use the readily available vinyl that was used for the seat surfaces. There's not much point in rebuilding mine as they are really bad (car sat open in the rain for a couple years).
BTW, I have some Black Sabbath 8 tracks somewhere that you're welcome to have if I find them. Also, do you know how to "ring" your tapes? It's a redneck technique for reducing the warbling effect that accrues with age. I'm not sure if I could remember how to do it myself but can remember sitting for hours at the kitchen table periodically ringing my tape collection. Yes, those were the days!
