that VIN is a 56 1/2T made in KC,MO, and C56 isn't a paint code, which were 3 digit numbers not usually put on the truck, and never anywhere but the tag on the firewall - as Brian says, USAF would be a unique number that wouldn't tell you any thing, as the custom ordered colors aren't listed in any paint code books - there's an "Alpine Blue", code 766 in the TF years that's close but lighter
what other "pertinent info" ya need?
