How available are mechanical parts?
To our benefit Chrysler believed in long production runs. For example, the basic flat head six was in production from the mid-thirties until the early sixties when it was replaced by the slant six. Basic parts for major systems like brakes, engine and transmission components are available from multiple suppliers. Many can be purchased over the counter at local chains such as NAPA. Because interchangeability of parts between the different Chrysler marques (Plymouth, Dodge, DeSoto and Chrysler) is very high, the search is also easier.
