You will need a hydraulic pump and brackets for an AMC straight 6, pressure and return hoses, a power steering gear box, and a power steering shaft, the lower coupling is different for power steering. I have no idea if the gear box bracket is the same or not.
That is a great tech write up and I wish I had found it before I did my change over. I would add that I could not find the bell joint to fit the gear box shaft and used a U-joint from Flaming river.
