Does anyone have a body/trim tag for a 1956 truck that they could post for Chris? The "tocmp" tag shown in the link by Bill (red58) is a 1951 "Body by Fisher" tag for an automobile.

Does anyone have a 1956 Truck Data Book or a 1956 Truck Restoration pack Specifications Manual with RPO codes?

As stated in the other thread , RPO 234 referred to Exterior Color though at least the first half of 1955. The "N" in 234 referred to Ocean Green exterior color. Trucks up to 1955-1st did not have trim codes, so the RPO codes (234 and N) might have changed meanings in late 1955.
