Technical Recommendations needed for a quality resister wire set Mopar flathead 6

Just painstakingly rebuilt my distributor in my 1939 Plymouth pickup. While doing this I found corrosion around some of the plug wires where they insert into the cap. Decided to replace them with new resistor wires which are required if I decide to convert to Pertronix ignition. Anyhow, I'm hesitant to buy anything these days. Too many cheaply made products. Can anyone recommend a company that might make a high quality set for my truck? Preferably Not made in China?

 

I used red wires on my 41 Coupe with the Langdons HEI........no idea where they were made but worked well........lol........andyd
