I was curious because my father's 66 GMC came from the factory with black tubs. I found something off the GMC site which I can no longer locate, that said paint the grill ivory and the tubs black. The problem I've found is that all the chevy trucks have already been repainted. I know the Chevrolet's are suppose to be painted white around the grills. Does anyone know of a paint code site, or something along those lines? I was just curious about it. Thanks for all the replies guys!
