I've got lots of upper body strength so I don't need power steering. But my daughters.. don't. I'd like them to be able to drive my bus, and power steering would go a long way towards that goal.
Mine has the steering gear outside the frame with the Pitman arm vertical, moving fore and aft. It's a 1965 C60.
The Cadillac V8 under its hood has a great power steering pump mount, so that's three bolts and done. Would I be able to find a Saginaw gear from a later truck that has the P/S built in, and bolt that on? Would I have to install an extra plate into the frame to stiffen it? And if I got an '80s one that said 'Metric' on it, what would be the practical difference? Would the Pitman shaft splines/diameter be different or just the fasteners?
