Anybody know where one can find the entire power antenna (motor, mast gaskets and fittings) assembly for a 66 .Has anyone used sny of the aftermarket units. Thanks

Keep watching ebay, you will also need the switch and the map light switch as they both mount in the center panel. I sold the extra switch I had but I might still have another motor assy. There is a place out west that can put a new mast in one if you find one that is broke.

FYI, if you are seeking authenticity, the parts are: C5VA-18850-A motor and tube assy.- radio antenna, C5SA-18919-D stanchion assy., C5SA-18984-B collar, 379701-S2 nut, C5SA-18939-B bracket (model 63) or C5SA-18939-C bracket (model 76) plus the misc. fasteners. The correct interior switch(s) is: C5SA-18863-A1 or A2 switch assy., C5SA-18911-B knob assy. and C5SB-13772-D knob assy. IMO, after market pieces would be much easier to find and adapt.

Thanks. The car orginally had the power antenna but some place along the way the motor was taken out and a standard antenna was used. I've looked at several psrts suppliers including Thunderbird Ranch, but no luck so far

So you have the switch already and only need the motor??

I need the motor and tube assembly, antenna and various fittings and gaskets for the mounting thru the fender opening. All I have is the power cable , switch, antenna cable and lower bracket. Do you have the 66 T-bird Electrical Assembly Manual? Look at page E6-4654-2 or page 58, view A.
