Hey, Guys,
I went through this wringer m'self with my '59 Apache. Of course, mine has a 350 engine with GM PS pump. The first time around, I used a mid-70s Corvette PS system which is virtually identical to the '50s truck PS system. The valve unit goes on the drag-link and supplies the ram unit that pushes the cross-link back and forth. Old Ford trucks used virtually the same system with a slightly different valve unit. I note in passing that the wheels don't make a sharp left turn due to the tire striking the drag-link. I eventually went to a 'real' PS box, but that's a different story (as well as a pain in the butt!) Incidentally, one can buy these remanufactured older Vette PS system fairly cheaply compared to the advertised truck units.
Regards,
