Original 1957 Packard Clipper Dealer Shop Manual Supplement. This Service Manual Supplement was meant to be used with the 1956 Studebaker Passenger Car Shop Manual for full coverage. It has the information, data and procedures that were unique to the new Clipper Models. This is what the Dealer used to service and repair your Car. It is in good condition with minor wear and soiling [see photos]. Very rare and informative tool for the Clipper Owner.
