I was going to use 1 set in a 1983 FJ40. However part number for a 1983 FJ40 is different and also discontinued. What is the difference and repercussions if I install this early wire set? Thank you

I believe it is just the length of the coil wire. Old is short since the coil was mounted on the block. Newer is mounted on the fender.

Thanks! If that is the only difference maybe I should keep the new wires and also keep the old coil wire.
