Hello all, not sure where to post this so I'll try here. I have a 1964 Suburban, all original, looks like it was repainted on the exterior once but interior is all original. I have been looking through threads on this site for a while now and for the most part have found answers to most of my questions. One question that I can't seem to find an answer to is paint color for the floor. My cowl tag says the color for the suburban is 558CB and I have found out that refers to Fawn and white. But I have not found listed any reference to the floor color. From what I can gather the truck floors were painted differently from the suburbans. Does anyone know what color the floor is or is suppose to be any rhyme or reason to what colors they are painted? I have posted several pics of my suburban for reference. Thank you in advance!
