Where do you buy and what kind? I have a 53 Chevrolet 6100 with the 235 engine and converted to 12 volts. I replaced the plugs and wires along with new cap, rotor, condenser and points about five years ago. During this time have less than 10 hours running time on the truck. Tried starting truck for the first time this year and did not start. Found bad wire, coil to distributor cap. Purchased wires and other parts from NAPA. Told them what I had and give me what you have on hand. The wires looked identical in construction to what I use on my 97 Dodge pickup. Now I am questioning if I should be more selective with parts that I have using on the 53 especially the spark plug wires. Wire construction has certainly changed over the course of 60 years. Appreciate your input.
