from 1970 Dart factory service manual:
slant six - 26 =/-3 amps
standard all other models - 34.5=/-3
heavy duty or Air Conditioning - 44.5=/-3
special equipment (fleet) - 51=/-3\
The fleet 51=/-3 amp alternator was mostly for police/emergency services vehicles and taxis - WHEN USED THE FACTORY BYPASSES THE BULKHEAD CONNECTOR AND RUNS THE MAIN WIRES (BLACK AND RED) THROUGH A GROMETTED HOLE DRILLED IN THE FIREWALL
Correct. We've posted these diagrams a number of times.
It's interesting to note that the assembly drawings for 1967-69 A-bodies illustrate the installation of the 60 and 65 special alternators. They are only listed under Fleet sales although I'm not aware of any surving examples on compacts until much later. Like on this'74.
Special Equipment alternators those years were rated 60 amp Chrsyler, and 65 amp Leece-Neville.
The later rear window defrost grid cars also came with a '60 amp' alternator. In this case it may have been a regular squareback. Still need to find an intact survivor to verify that. This option has a slightly different wiring to handle the load to the defroster. Pictures and diagrams here How rare is electric rear defrost?
