Tim, paint codes on the truck data plates and on Dupont chip sheets use 700 numbers, which is what I mean by 'paint codes per se', as opposed to RPO #s, which were a GM internal thing - Dupont used the paint codes on their info so body shops could find the color they wanted from the paint code on the data plate .... I've never seen any list of trim codes for trucks anywhere, that's why I asked about them

I don't have a Dupont sheet for 55 [Ditzler, with no codes], but all the other sheets I have use 700 numbers for all colors, solid [=A] or 2 tone [B, D, E, and for Fleetsides only, J & K] - one 59 sheet uses the 900's but it also states they're for Corvettes & trucks, others I have show 700 numbers, so 59 may have started cars & trucks using the same codes and it may not have happened at all plants at once

Frank, I'll look at my firewall again tomorrow, but the gas pedal mount you describe has to be 55-57, it changed in 58 to a 'flap' on the pedal that screws to the floor - otherwise there really is no difference in the cab shells
