Good original 1971 Pontiac Dealer Service Manual Supplement. This Shop Manual covers the Ventura II Models and was meant to be used with the regular 1971 Service Manual for complete coverage. It contains information, specifications, illustrations, diagrams and procedures for these classic Pontiacs. These are what the Dealership used to service and repair your car. Very informative and useful tool for the Pontiac Owner that is hard to find since it was a Dealer only item.
