    I'm looking at a 6" lift for my 71 and cross over steering. I know I'm after a 2wd power steering box, but not sure what years are best for my application. Any /forums/images/graemlins/1zhelp.gif greatly appreciated.

    Thanks

    Just pull the sector shaft from a 2wd box rather than a whole new one. The sector shaft is easy to remove just four bolts on top, take the pitman off, and it slides out. I got one at a yard for $9 /forums/images/graemlins/thumb.gif

    I am looking at this also but don't know much about it. Why a sector shaft from a 2 wheel drive? /forums/images/graemlins/dunno.gif

    its because the sector shaft for a 2wheel drive is keyed different than a 4wd one. You cant get the arm to point the right way with a 4wd shaft

    I believe you need a pre-'76 2wd box, they have the same fittings as your current box, this is what offroaddesign told me, I've not installed mine yet, but I'm sure they know what their talking about.

    The sector shaft in a 4wd box makes the steering arm go front to back, and trys to convert the front to back motion 90 degrees to left to right motion on the drivers side knuckle.
    The 2wd sector shaft makes the steering arm go left to right, then you add the crossover draglink over to the crossover arm on the passanger side knuckle. Left to right steering makes more sense to me. /forums/images/graemlins/smirk.gif

    Yah i grabbed a '76 box i think. I was looking for pre '77 stuff at the junkyard.
    Just make a mental note of exactly where your two hoses hook up at the top of the box, and find a 2wd box that matches. Then i sent it in to WTO had it rebuilt, drilled & tapped, and got the hoses and hydraulic ram for hydro assist steering. /forums/images/graemlins/thumb.gif Night and day difference even without modifying the PS pump. /forums/images/graemlins/peace.gif
