The hard part will be working the new wires back through the steel tube that they are routed through.

Either a little welding wire or a good piece of string + talc should help pull the new leads through, starting with the furthest one from the cap end.

Had to do something similar when fitting the wiring through the front wing stays/supports on a 1935 MG PA My late step-father and I restored. Not like we had a sparky's wiring rat we could have used.

Would be willing to bet that some spark may be leaking to the metal tube.

Plug wires can cause many issues, our pickup in 76 ran great on flat land, the trucks were passing us on the grapevine, new wires and ran good, those were resistor wires which is common , basically graphite string in rubber.

Hopefully you can get wire wires that will fit.

The old coils maybe only output 30 kv, the gap takes 5kv without fuel or compression.

The higher available voltage in New cars results in greater current in the spark.

The resistance in the wires greatly reduces the available current, results are very weak spark that may not ignite the fuel well.
