Yes, you are right to ask, Greg. There were 4 different two-tone interiors by late 1954. I assumed, perhaps incorrectly, that Nathan had a single color interior, since he asked about "what the color of paint the interior should be".
Nathan,
What interior color/colors do you have (do not worry about the technical/correct name - just describe the shade(s))?
Greg's question regarding vent-frame color is because a chrome frame would have come with an RPO 430/431 (Regular Production Option) that included two-tone interior colors (different from the RPO 390) Pulsar Gray interior color. Greg, does your truck have the green/green two-tone interior or the blue/blue?
The 54 that I am restoring will have the beige/maroon two-tone interior.
A variety of two-tone exterior RPOs were also available on standard cabs and panels in 1954.
