I recently purchased a 1971 300 SEL 4.5 as a parts car to be used in the resurrection of a 6.3. Obviously the engine and trans of the car will be of no value to me but what other mechanical sytems might I be able to use? Is the suspension system identical or are there small differences? The 4.5 was purchased primarily for interior parts but before I part it I would like to know what mechanical parts could be salvaged.
