Where to buy neutral safety switch, '68 Dart?

Besides leaking I was worried that my switch was defective as they had it unplugged at the starter relay and a short wire run from the relay blade to ground. I had never noticed but I assume that would let it start with the shifter in any position.

Ok. That is a sign it was possibly bad. My car was bypassed when I got it and they didn't tell me. I found out by nearly making a rear entry in the garage one day when I accidentally left it in drive after working on it. Scared the crap out of me needless to say. I fixed the switch immediately.
