That system was offered on GM trucks from 55 through 66. Although they used a conventional PS pump in the later trucks. One of the main drawbacks in addition to those Jerry mentioned is that it used the stock steering box. Any wear in the steering box or other components made for horrible steering. There is an aftermarket kit that Brothers and other suppliers sold for several years. I had one and I wouldn't recommend it.
