Original 1952 Chevrolet Truck Dealer Service Manual Supplement. This Manual covers the updates for the 1952 Truck Models. It was meant to be used with the 1948-51 Truck Service Manual. These have Information, Illustrations, Diagrams, Specifications and Procedures. These are what the Dealership used to repair your Truck. Manual has normal soiling and blemishing from use in a Dealership [see photos]. Very informative and useful tool that is hard to find since they were not available to the public.
