removing power steering pump.....

The manual rack is different than the power rack - while you it's possible to simply disconnect, remove and plug things, I wouldn't do it. Yes it will be very difficult to steer (more so than a standard manual rack), and the power rack was not designed to be used that way. Brakes and steering - two things you want to be sure are working the way they were designed. This is not an area in which to scrimp or take chances.
