Get the least expensive set of generic wires you can find. None of the fancy, expensive ones will make a nickel's worth of difference when it comes to lighting the fire on a stovebolt engine. Neither will a junk-tronics, for that matter. Super high voltage ignition systems on a 100 year old engine design don't make good nonsense.

Would anybody like to earn a fresh, new $100.00 bill? Just show me 40K volts applied to a clean, properly gapped spark plug running in a stovebolt engine! It's a safe bet, since it's impossible for that to happen.
