Re: \'66 CJ-5--Power Steering?
It all depends on what he considers a major modification. As was mentioned, AA has the brackets to hang the steering box so some welding has to be done (not splotchy, surface welds either). The front crossmember will have to be notched/reinforced or drilled and sleeved for the spud shaft to pass through. Some sort of draglink/tierod setup will have to be fabricated. The steering column may be something he would want to replace also, so bracketry for a new one would be necessary.
