Pretty happy. Replaced the antenna today. Much simpler than it looks like it would be. Basic How To process. Remove glove box straps, extend glove box door down. Reach in and around to remove antenna coax from the radio. Unclip antenna coax cable mounting clip from heater box. Unclip power wire located on the left lower glove box area. (find wires by following ant coax) Remove inner fender. Remove top antenna mount, external, spanner nut around antenna mast. Unbolt antenna. Remove body grommet.
Being a nice 26k mile Thunderbird Turbo Coupe I'm ok with the cost of a new power antenna, especially being a genuine Ford product. The cars are just getting old enough that once common parts are no longer available or atleast hard to source. The pre-89 power antenna mast inventory must be exhausted or alteast not profitable for the low sales.
Same battle with the Battery. Seems nobody stocks a 56 series at the dealer.
Atleast I now have my NOS Goodyear Eagle GT's mounted up waiting at the tire store!!
Decided just to buy a NOS complete power antenna replacement from an ebay seller. I have a feeling the older units are just a little bit different, for just a little more ($60 with shipping) I went with the new unit.
Replacing it might be a different story as it appears there are no connectors at the antenna, gotta pull the radio.
So I thought it would be easy to get a new replacement power antenna mast for my 84 Turbo Coupe but it looks like most only fit 89+ models and not the earlier cars.
