My car was built in Oct of 72. I remember seeing black plug wires on the car when I was younger.(dad bought the car new) I'm not convinced that early 73's came with orange wires but they are accepted as correct so that's what I installed. I really should have kept those other wires...didn't know that at the time.
I think we talked about this before, my 73 was not as early (November, 1972) and it had black plug wires. I was not the original owner but the car was only 4 years old and around 60,000 on the clock so I doubt someone changed the wires at that point, especially to Mopar wires.
