Confused about plug wires

[Sebscst]

Want to order new plug wires for my 78 sc. I want to route them over and down the fan on the right side and then 90 degree turn them to there cylinders. I have read that I need Carrera wires 84-89 to route this way but then also read that the distributor end is different on those wires. I’d like to get a set of magnecore or clewitts. Also I moved the coil to where the fuel accumulater use to be and need a longer coil wire. Any one know how I can get a set made. I tried contacting magnecore through email which went back and forth for a week know and got nowhere. There’s no phone number and there sales person sucks.
