BALLAST. This is the question. '61 Chevy 235 in a 1/2 ton Apache 10. There was no ballast resistor when I purchased the truck. I have not been able to find a part number for a ballast resistor available for this application. A mechanic friend of mine INSISTS that a ballast should be installed to prevent problems with the Pertronix module I installed. Pertronix instructions say to leave things as they were. Hoping someone can clear this up for me. Thanks
