change steering from power to manual?

[kittypancake]

Intuition tells me that manual steering would have less chance of failure. What would need to be changed to switch from power to manual? Is my thought process completely screwed up here?

I'm changing to make more room, not for reliability. I'm also changing from column to floor shift. The manual column is longer but you can buy an adapter if you can't find a column or don't want to replace it. The gear box also needs to be swapped out, obviously.
