1988 350i Steering Rack

[Pigboger]

1988 350i - Looks like I am going to have to replace the steering rack. Not power assisted. Is anyone aware if what the original part was and if it is a straight replacement or needs modification ? Would it be easy to convert to a power assisted unit ?
Many thanks in advance.

Thanks Ziga.
The rack is the problem. Not MOT failure but is starting to show a little play. Would rather sort now. Have mixed feelings about PAS. You are right though, best left as is. I have a Tamora and wrongly compare the two cars for driving experience which are of course like chalk and cheese.
Thanks for the advice.
