You can use a vitara power steering setup with a BenT wedge adaptor, or source an early G Jimny (98-00) p/s kit that will bolt in with only minor mods (bending some hard lines)
It doesn't really matter too much what year vitara as you will be using an adaptor plate anyways.
I believe there is a thread in the "Good Tech" section that I'll try to find and update here with.
