Hi Jeff and Midlife,
I suspected as much regarding ordered vs delivered but never really knew. The car in question is the one in my sig. It is a San Jose built, '65 fastback with a scheduled build date of 10/2/64. If the door tag is correct it had a 4 speed trans and a 3.00:1 open rear. Unfortunately, it currently has a '71 or so Maverick six cylinder 3 speed trans and a 2bbl mystery displacement small block V8 Ford engine. Even the aircleaner assembly is wrong (Fairlane/Galaxie type).
So a good guess would be the original owner couldn't wait for a 4 speed A-code fastback to be built and had the dealer search for one? Too bad it has been 52 years. I doubt Galpin Ford would have any records of the sale.
