I have a friend looking for a complete setup, including the dash control switch. This "early" design has the thin, rectangular grill for the rear package tray. Buick changed in up later in 1970 for whatever reason. That said, if anyone has one they need to get rid of, please let me know. Thanks in advance!
Brett, This was in my car since 1980. Not exactly the same though. I do not have the switch. It was wired with a toggle switch.
