I have finished (for now) working under the dashboard of my GMC 5500 truck and have moved on to repairing doors, including weather strips. This truck appears to be an early 1966 model that was sold in October of 1965, but the cab shape and doors look more like those on 1967 pickups. Since parts seem hard to find for 1966 GMC medium duty trucks, can anyone tell me if these doors are the same size and design as are found on the more commonly available 1967 pickups?
