Hi all, my name is Steve. I've got a 1991 Chevrolet Camaro Z28 with a standard fixed antenna, and would like to convert it to a power antenna. A couple of weeks ago, I purchased a new power antenna kit from a dealership. The assembly came with the mast, motor, wiring with fasteners and brackets, but on Modern Day Muscle's website, I noticed a power antenna mast nut, do I need that? If so, what other parts are necessary to complete this conversion? Your responses would be greatly appreciated.
