First you need a manual box.Junkyards,e-bay,swap meets etc.
Flaming river has a trick unit but pricey.You will also need a adapter if you are going to stick with the same power steering column.Or install a manual column.The adapter seems easier.I cant remember if they share the same pitman arm.Either way that's simple to figure out.
Take the power steering parts out,install your new manual parts and your done.
Hope this helps.
