    steering box should be the same up to 1980 I believe, those all used a flare type fitting then 1981 and on GM went to the O-ring style fitting on the hoses.

    Yup, had to figure that out that exact thing when I won a setup from WTO and was buying a 2wd box from muddytazz to send them....

    I've changed several leaky power steering boxes on GM 4x4's--in my experience the boxes from 69-72 fit the later models,with the hose changes noted already in the previous posts--the steering colum end of the box comes in at least two different spline diameters /forums/images/graemlins/deal.gif(I've only seen 2,maybe more?)--this means another trip to the boneyard to get the "rag joint" and steering shaft extention.This usually is discovered on sunday,when the truck is all apart,and the boneyard is closed! /forums/images/graemlins/angryfire.gif(nothing like calling a co-worker for a ride and he says"oh been fixing your truck again,aaayyy") /forums/images/graemlins/blush.gif

    any chance of interchanging the input shafts on first gen boxes with that of a second gen van?
