Hi Jimmy , looking at the metal on the dash I would say silver . The seatbelts and door panels are blue. So I would say silver with blue interior. Have a great day and keep them on the road!
Those generation Chevy fullsize pickups were the first to have a fleetside box which was introduced in 1958. At the middle of the 1955 model year when they first began producing those generation fullsize truck models, a Cameo pickup was introduced which looked like a fleetside with the same amount of box floor space as a stepside. The Cameo pickup was dropped in 1958 because of the new fleetside pickup.
