 Differences between the 1950 Special Deluxe and the 1951 Plymouth Cranbrook are relatively few in number and scope, with interchangeable glass and doors, but different rubber seals; lack of woodgrain on the instrument panel; plastic brake handle instead of chrome; and other similar changes.More substantial was having what had been the hood release handle function as the overdrive control.Fender lettering and other badging necessarily changed as well.
