The steering box PSC sent us was an '80-up metric O-ring type with a 13/16-inch, 36-spline input shaft and a big bore piston for rugged use. Although we currently have no plans to add a hydraulic ram assist to the steering, our box came tapped for the lines and our high output pump can handle the added volume. If we ever do find a need for hydo-assist, it'll be as simple as uncapping the ports and hooking up our ram lines.
