Found this site: http://autocolorlibrary.com/scripts/depot.exe?pgm=aclgate.bbx Looks like it may be a good resource for color matching.
I use that site every day for the Centurion registry. If I don't know a paint code, then I look it up there. It also lists trim code colors.
These guys are just great. Had them send me some interior spray for my '71 Sandalwood interior. Didn't match the first time. I then sent them an underdash steering column piece to use as a model. They shipped an exact match @ no additional charge.I would see a full refund if they couldn't make a match.
