Original 1976 GMC Truck Data Book. This Dealer Reference Book was used to educate Sales Staff on the Full Line of Truck Models and to help Customers make their purchase. It shows features, options, specifications, and pricing for the Full Line of Light, Medium and Heavy Duty Truck Models, including Motor Home and Bus Chassis. It is in the original GMC Truck Ordering Guide Binder and is in good condition with minor wear, blemishing and soiling [see photos]. Very rare and informative Dealer Only piece.
