Retro-fitting power steering.....

[Hedgehopper]

I am about to change my manual rack for a powered version and need a bit of advice as the Search Engine is still down.

1) Can I remove the manual and then fit the power-rack without removing the Y-piece?

2) What is the Land Rover part no. for the pump and what model did it come from?

3) I believe there is a reputable power-steering refurbishing company in the Bristol/Bath area? I know about Kiley Clinton but was looking for someone closer to home.

Any advice will be appreciated.
