The ram assist power steering was used on Chevy cars up through 1964, Mustangs through 71, Corvettes to about 1990, and many 4wd and construction equipment. It works very well but on lower vehicles the hoses were hard to keep keep up out of the way of snags. On a big truck it should work fine. To install you mount the control valve on the pitman arm end of the drag link, make mount brackets for the ram on the frame rail and the tie rod, mount p/s pump on engine and run the pressure and return hoses. Not a complex install at all and changed none of the original design or parts. Pics of the set up on a 1940 International with straight axle.
