Good original 1960 Chevrolet Truck Dealer Service Manual Supplement. This Manual covers the updates for the Tilt Cab, Four Wheel Drive and Powermatic Transmission Trucks for 1960. It was meant to be used with the regular 1960 Service Manual. These have Information, Illustrations, Diagrams, Specifications and Procedures. These are what the Dealership used to repair your Truck.  Very informative and useful tool that is hard to find since they were not available to the public.
