Hi 49chevyman
I also have a 49 chevy pickup and asked the same questions back in December 07.. Thought you might be interested in what we had to say on this subject. The forum was started by fellow bolter, czechman 12-18-07,followed by informative discussions by 65 panelmike,adpickup,and info from tcledderman. Mostly about interior vintage paint codes. This informative forum resulted in a Dupont paint code called "GRAPHIC BROWN METALLIC" Dupont jobber
code 27467. The back of my radio delete plate still had good paint so I cleaned it up and once the Dupont color was mixed up it was a dead ringer. It has a grayish champagne with hints of brown. I was very pleased with this color hope this will help.
