Help - Car Won't start

What kind of tranny is it C4? I believe the swith is nylon and could just be broken at that point. Take a look at it.

sometimes the shifter is "sloppy" and won't engage the neutral safety switch in P. you can replace the worn bushings(there are 2) to tighten up the shifter-pretty easy to do

I just got a hold of an old family Mustang that had been neglected. It is a 67 289. It won't start or turn over at all. I've searched several threads, including this one, to find where to start looking to solve the problem.

Are there any other basic things to check other than battery, starter relay, and neutral safety?

Thanks for your help in advance. I don't really know what I am doing, so I am sure you'll be seeing a lot of me in the next few months.

the battery, starter relay and NS should be the main ones. I had a problem once where the car cranked but no juice, turns out the 12v lead to my ingnition coil was grounded somewhere.
