Any one know what boxes fit other than the 67-72 medium duty trucks? does the steering box only fit the medium dutys? not too many yards here that have any older stuff around especially meduim dutys. Thanks

If so does any one where I can get this set up?

I'm just stating that my steering box is heavy enough for my big truck. I'm not sure if you'll need a standard pick-up box or a 4X4 box for your truck,
Good luck,

However the control valve is in the box so you will need the box ram hoses pump and linkage for the ram attachment. This system works much better than most power assist setups. Because the valve that controls the ram gets its input from you at the boxes input shat instead of from the box at the draglink. This gives much better road feel much like a standard power box. This box will look like a normal Saginaw box but the output shaft is horizontal like your stock manual box instead of vertical and it has four ports instead of two. An input a return a left turn and a right turn port. | | | | | Joined: Jan 2007 Posts: 176 Wrench Fetcher | | Wrench Fetcher Joined: Jan 2007 Posts: 176 | Thanks, The problem is finding these parts. these trucks are few and far between around here. Any one got any trucks they are parting out?

It may fit your truck nicely? Can you post a picture of the original setup?
