Well some joker broke the top of my antenna off. So I removed the stanchion nut, pulled the top part of the antenna/nylon toothed cord out, and removed the 14 mm nut. But the main antenna shaft only comes up so far and won't come up any further. What else has to be done so I can replace the shaft? If I were to go with a standard whip antenna, is there a stanchion that will cover the giant hole in the fender? Mike
