Excessive play in steering wheel ?

This could be a real dumb question. But my 66 dart has some serious play when steering. Like several inches each way when I turn the steering wheel. However the power steering is fracking awesome. Turns easier than my new cars.
So what is the culprit ? And is it an easy fix? Are there any other fixes you would do at the same time? Like shocks?
I want to say that I have worn Tie Rods. But I don't really know what that means.

No question is a dumb question because everyone is a beginner at everything at some time in their life.
Where in LA are you? I'm in Torrance. If you are close I can show you the parts of what makes your Mopar special. I can turn you on to specialists or show you how to do something.
