Original 1940 Plymouth Dealer Preliminary Parts List [dated October 5, 1939]. This Preliminary Mopar Passenger Car Parts Book is what the Dealer used to order available Factory Replacement Parts to repair your P9 or P10 Plymouth Model. The Preliminary Books were sent to Dealers to use until the regular editions were printed. It has an Alphabetical and Numerical Index, Part Numbers, Description, Application, Quantity and Illustrations for the Replacement Parts for these Cars. It is in good condition for its age with some wear, soiling and blemishing [see photos]. Very informative and rare piece for the Plymouth Owner or Collector.
