Hello,
I removed the air con pump and the power steering pump at the same time then replaced the belt with a fiesta non-pas/air con belt and fitted a manual rack. I had to space the altenator out a little bit to take up a bit of slack, but you'll see that in the previous posts. If you keep the pas rack you need you source pas bits from a non-air con fiesta and swap bits around, there are a few posts that cover this too. I decided against this and went a simpler route (sort of) but it depends what you want the car for, mine is purely a track car, so I'm not bothered about parking etc with pas, I just wanted good feeling/feed back.
Hope that helps.
