".....`58 neutral/starter share the same button haha , it took me a bit before I could hit neutral with out grinding starter....."

The wiring from the N button switch to the starter solenoid is supposed to go thru a vacuum switch on the intake manifold that opens the circuit when the engine is running. Over the years I've seen far more bad switches (always closed) or wired around or the ignition switch replaced with a more conventional acc/off/run/start switch than I have seen cars that actually work the way they are supposed to.
