Plus I show it is for a 1969 6-8000 series car. He is correct that it is for the left side so he is not completely off base. To fit a GS or a Custom, it would have to be a 16 inch armrest
Well, I actually have 2 NOS black 16" LH ones. Would love to trade one for a RH if there's one out there. Ended up with one of those deals where one was for sale, but I couldn't remember which side I needed. Took a chance, and ended up with duplicates, still needing the other. Anyone got a RH out there?
