this is a real longshot but does any have a set or know of a set of side window louvers for a 79 Century a company offered them in the late 70's and midway to the 80's i have the book with them pictured but the company is no longer around it was in the Detroit area like I said its a long shot but this is the place to ask
the company was called Diversified Fiberglass in Pontiac Michigan they sold body panels and kits for the Century and the Regal I know it was not a very popular body style but its still a cool Buick
