Zombie Dart! '72 Dodge Dart

Hey man, keep at it, its looking great. I've just been playing with the truck. Just ordered an RPM Air Gap and I bought a Holley 750 vac sec off a coworker for $60 that is brand new. about to order a decent cam and headers and a 4.56 gear for that 8 3/4. I'm determined to smoke my roommates stang. I'm about replace rear main and ha lol. Ive already replaced the distributor. How do I unbypass the neutral safety? Btw, I got a key made for it. Never again shall it come to work.
