For sale is a NOS 541963 power antenna mast assembly. My 1969 Pontiac book shows it to be correct for 1962-69 full size Pontiacs and 1964-69 GTO/LeMans. This is the assembly line correct version with the longer mast. This part number later changed to 9795957 which was shorter. The price book shows these part numbers fit Buick and Oldsmobile as well.
I do not have those parts books so please verify your application on those models. I fully extended this so you could see it works.
