Picked this gem up in Carlisle with the switch and the guy had another switch to boot. Big score. The web never lies but I'll believe it here regardless. Camaro, Chevelle, something else?
68 Camaro
I have one of those in my 69 Camaro SS.
My '68 SS/RS came with one as an option. I think they were more common in full size GM cars. I've never seen many of them, especially in Camaro's.
I am guessing that is a rear window defogger? It looks like what my 1967 Camaro has.
Sorry, I thought it was understood that it is a 2-speed rear window defroster.
