Hello Droninsgirl,
Welcome to the "Bolt". I would think that a '67 would have a paint code marked on the VIN tag. What about in the glove box? It seems that around that year, a lot of information used to be on the inside of the glove box door. Hang in there, someone with better information is bound to come along. It's been quite a few years since I owned a mid 60's Chevy truck.
