Off the top of my head, a new[er] steering box [with pitman arm? Don't know if it's different between standard and power steering], power steering pump, hoses to connect the two, and a new fan belt. Should be able to scavenge at the wrecker. Bradner Salvage [if still around] always treated me good. I don't think it would be that hard, no modding involved, simply R+R.Take pics of the donor so you can remember where things go.
p.s. I've never done this swap to this new of a vehicle, so there may be other things involved. You're doing the right thing by asking questions and doing research 8).
p.p.s. If you don't have a puller, you can loosen the drag link [might not be the correct term] from the pitman arm by hitting the pitman arm on the nose right where the drag link attaches with a 2-3 lb sledge hammer, after loosening the nut. Leave the nut on slightly as the drag link will drop quite suddenly. If I knew how, I'd show a picture with an arrow where to hit... can anyone help?
