Does anyone know if there are any difference between a 3/4 ton power steering box vs a half ton box? Can they be interchanged?

Any info is appreciated.

Thanks.

Scott

I may be wrong but I think just the pitman arm is different...

the gear box and the pitman are the same, 68 - 72, 1/2 ton through one ton.

Thanks!

What about 4x4 vs 2x4.....I know the pitman arms are different there, but could the box be used in either?

No, the output shaft is keyed differently (90 degrees off IIRC).
