This large Parts Book [effective March, 1988] covers the Light Duty Series 10-35 GM Trucks [Pickup, Blazer, Jimmy, Suburban, Van, Forward Control]. This is what the Dealer used to order available Factory Replacement Parts to Repair your Truck. It has Part Numbers, Group Numbers, Description, Quantity, Application but does NOT have Illustrations.
