This CDrom gives you assembly illustrations down to the last nut-bolt and screw. It shows exploded views of nearly every mechanical part of the truck-and includes part group numbers. Use this CDrom to help you disassemble or reassemble parts of your truck-and or to help identify parts that may be missing or incorrect. It contains production and regular production option information. That means that you get information on the base model all the way up to fully loaded. You will find illustrations for body mounting-frame-front and rear suspension-brakes-engine-transmission-fuel and exhaust-steering-wheels and tires-sheet metal-electrical-radiator and grille-bumpers-and much more. There are exploded views and illustrations on just about every one of the CDroms images-with wiring diagrams-torque specifications-and handwritten revision records. This CDrom covers the 1955-1956-1957-1958-and 1959 Chevrolet Truck only. Like all assembly manuals-this is reproduced from a book made for use inside the factory-and never intended for the public. Therefore-the images like the print in original assembly manuals are occasionally light. This is the best quality available. This CDrom has 737 pages and is in new condition! Go on and tear that pickup apart! This CDrom will help you put it back together.
