I drove a 1964 B-Model with a 262 cummins 5X4 trans It was a Oil Tanker which we turned into a Dump truck. It was set up with Air Power Steering Which worked fairly well. Now A friend a I have a 1964 B- 77 with a 335 cummins 5X4 this was a Lumber truck it has been mostly restored it also had Air power steering, but the steering Ram is gone and Iam sure the control valve is junk as well,Is there parts out there for it? I also have a Ross Power steering thats on a Diamond T (Oil power Steering) can I swap that on the Mack.
