I removed the power steering unit (everything) from the 1992 Caravan I'm putting a 1.6L turbo diesel in. I replaced it with a new manual rack. It steers well at rest because the gears are different - 3 turns lock to lock for a P.S. and 4 turns for a manual. Here are some photos and description of what I did... half way down the page.
