This original 1978 Chevrolet Truck Data Book is in good condition, it is not in the correct binder- there is no GMC material in this. This was put together to be an easily accessible resource for the dealerships' salesmen. Included are graphs, diagrams, ordering codes, options and accessories, and more for the LUV, El Camino, Pickup, Diesel Pickup, Blazer, Chassis Cab, Suburban, Sportvan, Chevy Van, Cutaway and Hi-Cube, Step-van, and Motor Home Chassis. This album is well put together and is a must-have for any collector!
