I'm with you here Barky, I much prefer the non assisted feel although I have not experienced it on my own car yet, my thinking is its a ton car so can't be too bad lol. Many have done it and some don't like it, from my research it's usually the people who are using their cars as a daily that don't like it, take from that what you want.
Its easy really, you have two options, sack off the ps pump and re-route belt with a smaller version or replace the alternator mount (cup brackets) with a Volvo bottom bracket.
Then you can replace the rack for a dci rack and fit your track rods and ends or you can do what I have done which is keep your standard rack that keeps the same turns from lock to lock and loop the pipe on the rack and blank off the connections at the pinion. Fill the rack with oil and the pinion with grease.
