Found a paint chip book form Rinshed-Mason Products at the flea market this weekend. Some paint chips date back to 1963, but at the back of the book there were some "Truck" paint chip pages. These are the ones for Chevrolet & GMC (1964-69,1970,and 1973), page two for each is the back of the pages for two tone color codes and interior color codes. I scanned them full size, no color corrections, so if the page is yellowed that is how it actually is but the chips are true to color.
Hope this helps someone.

If you think there may be a color chip in the book that you may want to see drop me an email and I will look for it and scan it for you.
