I guess they just came with steering assist? He wants a true power steering. Yes locally there is a yard with a lot of pickups in it just trying to narrow it down.
Sorry Hops , This is one of those times that I'd have to be there to figure it out . But what I would do is take a bunch of measurement's and compare them to say an early 70's Dodge truck . Pre 76 4x4 would probably be my first choice , just because the way the steering box and pitman arm's are set up and then take it from there .
