I think they are called dash "vents" or "registers". I am not aware of any reproductions. Have you tried the Parts Wanted section? What condition are you looking for?
Driver quality would be fine. Mine may be too far gone to salvage. So I'm looking around. If memory serves, there are 3 in a '69 Skylark. I'd bee a good item for someone to reproduce since they wear out and get loose. I'll check into the Parts Wanted, but they may be no better than mine already. Thanks
I found a set of originals since this posting with help rom you guys with the proper search terminology. Thanks
