Power steering switcheroo

I have a '72 Swinger with /6 and power steering and automatic transmission (column shift) and a '71 Swinger with /6, manual steering and three-on-the-tree manual transmission. I want to swap out the power steering into the '71. I am thinking it will require only switching out the steering shafts (I want to keep the housings in their current locations of course) but can it really be that simple??
