This CD is a replica of the factory manual. This is the Parts List Catalog created by the factory for their service parts department. It includes body and chassis, text and illustration for each part on the shelf during the years indicated. The text section gives you the part number, common name and application. The illustration section gives you labeled blown up "exploded views" of the parts, showing what they look like and how they fit together with their adjacent parts. It is therefore also helpful as a sub-assembly manual.
