Original 1978 Chevrolet Truck Dealer Product Training Portfolio. This Data Book is what was used to educate Sales Staff on the new Truck Models. The original Binder holds Data Sheets for the Full Line of Truck Models. These include Pickup, Blazer, Suburban, El Camino, Van, Luv, Medium Duty, Step-Van and F/C Chassis. It highlights the Features, Options and Specs for these Models. It is in good condition with minor wear, soiling and blemishing [see photos]. Very rare and informative piece for the Chevy Owner or Collector.
