I just need the top part, above the winding, that attaches(and tunes) with the 2 Allen screws. No longer many CB shops around to ask about those antenna pieces. Truckstops carry Wilson centerload antennas in the CB racks; I hate to buy a whole antenna just to use the top part (without being sure it would even fit), unless the mount also fit and I could just change the whole antenna. Still haven't looked at it; took wife out to dinner on it instead. Waiting for my boy to ship me the intercoms I gave him when I sold him my last Venture; he doesn't like them, isn't using them and now I need them back...
