On my 72 Cuda, I turn the key to start, and nothing happens. Starter Relay has 12V to it from the battery. Was thinking might be the Neutral Safety Switch, which I removed,
but can't get a new one on there due to clearances. Can I just ground the wire coming off the starter relay, which goes to the NSS,
so the engine will start. Can I leave that wire connected to ground? The connection on the starter relay that gets the 12v ignition start signal
is also getting 12 volts. thanks Or maybe I just need a new starter relay? thanks
 
Yes as a test and temporary measure.

Yep, you can permanently ground the NSS wire.
Just be careful, engine will turn over in any gear.
Accidently left mine in drive, when I hit the key, it started and moved forward, luckily nothing in front.
 
First and easiest is "clean" the battery terminals. Then jump the starter relay to see if everything else is good. With our not daily drivers, terminals seem to be biggest problem. I learned that first hand a while ago. To jump relay take a screwdriver and touch big screw and little screw just below it. I see your fairly new here so that is why I said those things.

That can happen. A friend ran his Super Bee through the back side of the garage. Bypassed NSS.

I did away with the clutch switch years ago. 71 Cuda 5 speed, when I park I always make sure in neutral and apply parking brake. I don't like the idea of pressing on clutch pedal and adding stress to the thrust bearing when starting engine.
