Steering column

I am going to be putting a floor shifter in my 75 duster after i put in the new motor/tranny, and the steering column i have has the shifter on the tree. I found a '69 dart at a salvage yard that i have been picking parts off of and it came with a floor shifter, so i was wondering if the steering column on that would fit into my duster? Would it hook up to my steering gear box? And if it doesnt fit, what would be my best move as to getting a steering column without the shifter on the tree?
Thanks,
Joe
