Original 1960 GMC Dealer Master Parts Book. This Parts Catalog [dated June, 1960] covers the Models 5500 Thru 9000 Trucks. It has Part Numbers, Group Numbers, Description, Quantity, Application and some Illustrations. This is what the Dealer used to order Factory Replacement Parts to Repair your Truck. It is in very good condition with minor wear and blemishing [see photos]. Very rare and informative piece of History that will be a great tool for the GMC Owner or Collector.
