Johnny B,
Napa probably has belden or Echlin. I assume your running a flat 134 or F head134. Either eng is low tech and will run fine and dependable w/ solid core wires. Any benefit obtained using resistance would be unnoticeable. Solid wires will take more abuse by people unfamiliar w/ proper wire handling. Google Aurora Electronics, click products, then ignition wires. a small tutorial. They do list a set for '55 CJ3B. No doubt pricey and the rest of your ignition system should be in good shape to match. Spiral w/ ferrite is high quality. Google Taylor Spiro-Pro for more info. David
