SiInce the starter motor has a complex inductive reactance when spinning, it does not draw twice the current at 12 volts than at 6 volts. The current is somewhere in between, so 12 volts works fine. I have also converted a couple old 6 volt cars to 12 volts without replacing the starter. The 12 volt replacement starter solenoid is Sierra #18-5807.
