Haha, I just went through this two months ago for my 73 Charger!

I went with the Stage III and am very happy. It feels about 75% like a modern day sedan steering to me. It isn't the pinky steering anymore like the factory boxes but no too firm where it's not fun to drive....even at low speeds. I heard if you have fast ratio pitman/idler arms, then the stage III can be getting pretty firm but with factory ratios, I love it.

Go with the Stage III!
