its pretty easy to convert it. Let me see if I can remember all the parts. Power steering pump, a serpintine belt, powersteering box. I think that about does it. If i forgot anything maybe some other can add to the list.
i know when i converted mine to power steering i had to change pitman arm as well. i took the power steering from a 92 and put it in a 88. i think the ones from 86-90 are different from the ones from a 91-93.
