The VIN is: 6R07C203428. Any place where to find the real special color order ??
No. Ford did not load the data for 1966 and earlier to a computer so that way is out. San Jose did not use buck tags in 1966 so no go there either. Unless you find a build sheet hidden in the car (under the carpet, wrapped around the under dash harness), still no. The original window sticker would tell you, but it's probably long gone. Even with the door data plate, no. The plate would have a blank paint code, but would have a four number special order number as part of the DSO, making it a six number code. That code would be on the district order and factory order which would then give the paint's color. In other words, no.
You can make some educated guesses:
Body Type - 65A (assuming bucket seats);
Color - (blank);
Trim (your choice of black, aqua, blue, or white combinations);
Date - 20C (close);
DSO - (your choice, with some reservations, like smog - does your engine have smog?);
Axle - C (2.80:1 was standard for a "C" code engine);
Trans - 6 (assuming a C4 automatic)
