Good original 1996 Chevrolet and GMC Dealer Service Manual Supplement. This Manual covers the G & PG Chassis Models. These were used by the Dealership to Service and repair your Truck. They include information, specifications, procedures, illustrations, diagrams and trouble shooting for your vehicle and were meant to be used with the regular Service Manuals. Very informative and useful tool that is hard to find since they were not available to the public.
