You need to buy the so called V8switch and the tumbler/key that fits it. This switch has the far fight rotation momentary start position and springs back to run position.
If you need help in wiring this switch, let us know.

FIY: Your original "stomp" switch, On/Off, is worth some money.

I don't understand any of this "I tested another v8 58 Apache that turned over with the Key switch. The current motor and trans are running when I give 12v directly to the ignition wire from the battery."
But anyway, buy the switch I linked and all your wildest dreams will come true.

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
