Original General Motors B Carline Service Manual. This GM Dealer Shop Manual covers the Chevrolet Caprice, Pontiac Safari, Oldsmobile Custom Cruiser and Buick LeSabre Station Wagon Models. This is what the Dealer used to service and repair your Wagon. It has information, specifications, troubleshooting, procedures and illustrations to aid in repairing these Cars. It is in good condition with normal wear, soiling and blemishing from use in a Dealership [see photos]. Very informative and useful tool for the GM Wagon Owner.
