4 door steering shaft same as 2 door?

My demon was originally a ps car, I put a manual box in it, then took the shaft out of the dart collum and put it in my original Demon housing. I didn't really think there was a difference in the wheelbase. Thanks for input!

Wheel base has nothing to do with it. You didn't follow what Dartnut said.

The 70 is a one year column to be correct and that is why I asked what year your Demon is?
