Dont remember if a factory option..didn't see it in a parts group list though.
I know of 18 Birds that don't have it, 2 that do.
"Bird glass ....no one can pin this one down as I've had every possible combo get these don't think it was a late model addition or early model deletion".
"*MYSTERY: Why did some Firebirds come with Deluxe Seat Belts when it wasn't noted on any of the documentation ? My '68 RA I Conv. has it's original, date coded correct Belts (deluxe) yet, the documentation says nothing about Deluxe Seat Belts. I've never seen any correct, original '68 Firebirds with the 'Coach' emblem Button (not to say none were built with them) Seat Belts are yet another mystery- right up there with the 'Bird' Glass."
