I might have one from a ‘70 I parted out years ago. What makes the early cylinder different?
The early switches for the 1970 model have a wiring pigtail harness soldered to the part of the ignition switch fastened to the lock cylinder. That ignition wiring pigtail has to fished thru a narrow passage in the upper steering column, and then to a connector hidden behind the dash board.
On the later model cars the electrical part of the ignition switch has just several spade wiring connectors on it with the separate wiring harness already in the steering column, so you just have to connect a set of spade connectors to the rear of the switch. There is no need to fish a bunch of wires thru a passage in the column and into back of the dash board to a large connector hidden behind the dash board.
