Correct Plug wires for 73 340 Challenger with electronic igintion

[montanamopar]

I'm looking for someone that has purchased "black Mopar" model year coded wires for a 73 Challenger 340. I have ordered 2 sets off ebay only to have to retuned them because 3 or 4 wires were too short. I am trying to take this car back to its original state as much as possible but can't seem to find the correct plug wire set that fits this car.
as answers out there for me?

Try Year One, They sell date coded sets for 340's. I think they date code thru 8/72. Not Cheap at 85 dollars, but if you are looking for the correct ones, check them out.
