Good original 1964 Chevrolet Dealer Service Manual Supplement. This Shop Manual Supplement covers the 1964 Biscayne, Bel Air, Impala and Impala SS Models and was meant to be used with the 1961 Shop Manual for full coverage. It contains information, illustrations, diagrams, specifications and procedures to service your car. These are what the Dealership used to repair your car and are very hard to find. Good condition with minor wear and soiling [see photos].
