I just repaired the power antenna mast on my 1979. Does anybody have a photo of the correct mast finial tip (ball) for the 1979 power antenna? The Tech Manual describes the correct finial as, "ball with parallel sides, making it roughly the shape of a small cylinder, rather than spherical." Here a photos of what I'm working with. The taller one is the one that was on the car, however the previous owner did state that the Power Antenna was replaced. The shorter saucer like tip came with the replacement mast. Are either of these correct?
