I am looking for a power antenna mast and drum for a 1968 impala. My antenna is mounted in the trunk on the passenger quarter panel. I have a working motor, but need the mast and the drum that goes in the motor. The drum fits on the motor shaft and winds up and down to move the antenna. If you have the complete unit I will buy the motor, mast, and drum (even though I have a working motor already) if you are willing to separate the drum and mast that works too. Please let me know.
