What coil..?

then I guess the question is, what coil (part number, brand, link etc etc) could be used with the factory electronic ignition that would allow bypassing the ballast resistor. I think Andover Coils bragged about this, but I cannot find a dealer.
Pertronix Flamethrower with the 3 ohm coil resistance is an option. PN 40511.... or 40501 if you want chrome! LOL
