The three (and variable) speed Prestolite sourced motors will pretty much swap
from at least 1967 to the end which was 1977. However, the park switch
plate changes depending on the model the motor is destined for.
To adjust this is easy to do - just loosen the screws (do not remove), pull the plate up a bit, and rotate it to the correct position for your car as shown in the above photo. (Source: Mopar Action)
