First post, been lurking for about a year. I'm trying to find some information on the underdash A/C unit in my '66 F250 Camper Special and haven't come up with much. The only marking I can see is on the fan housing which says "Lone Star mfg" in Fort Worth, and then a serial number. Maybe someone here has seen one of these?

Not genuine Ford. Ford offered two 'dealer installed' A/C units, both types were hang-ons.

The bezel of the A/C unit with the Ford crest is exactly the same as used on 1963/65 Falcon/Fairlane & 1965/66 Mustang.

The 'Rotunda' A/C looks similar, but the round registers are a different size than used on the above unit, the two switches are in a different location.

With Ford crest: 1963/65: The area around the 4 round registers is painted light argent, 1966 is painted charcoal.

Both of these units: The bezel is about 22" long.
