want to upgrade to a mini-starter for my 64SS with a 327, AT and Pertronix ignitor in the distributor. Which one would you recommend? Was thinking Powermaster, but not sure which one will fit without issues. My 64 has factory wiring, so I assume I only need the positive battery cable & purple wire and I should tape the other wire to the harness? I see a Powermaster XS 9526 at Summit, seems like a good one. Thoughts on that one?
