I need some advice from someone who has added power steering to a van that
originally had manual steering. A friend is going to do the conversion on
his van in another country, and we'd like to be sure he takes all necessary
parts along. So far we have the pump, lines, and steering rack. Are there
any other front-end parts needed, like steering 'knuckles' or shafts? I
haven't done one myself, so I can't give him experienced advice. Anyone?
Thanks in advance!
