    Here is the question, does anyone or has anyone replaced the 4wd steering shaft out of a 4wd box into a 2wd box, and if so, where did you get the 2wd shaft from?

    Second question, will a 2wd steering box from a 73 or later 2wd GM or Chevy truck work on a 72 first gen blazer?

    Or will a Ford 2wd steering box work on a 72 chevy first gen blazer?

    Exploring my options for the crossover steering setup.

    I already have the milled passenger side knuckle, and the steering arms for both sides, now I have to come up with the 2wd box and the heim joints, and the tubing to finish the setup. The 2wd box from Adanced is $160.00 and I was looking for a cheaper alternative.

    I saw a bunch of 2wd 73 and later boxes at the junk yard last weekend, but I am not sure if they will work, and or if the Ford boxes will work.

    Anyone have any answers?????

    Any help would be greatly appreciated.

    I believe WAXER just did this on his rig. May want to drop him a pm.

    Not quite sure I understand the first question. BUT, if you're asking, "Will a 2wd pitman shaft fit in a 4wd steering box?", the answer is yes. I just did it last week. I was going to pull it out of a junk yard but ended up having a friend with an old 2wd box, just yanked the shaft and put it in mine. These are series 800 boxes for both 2 and 4 wheel drive. Just look for a GM box on a 2wd truck with the cover plate w/ 4 bolts on top and the preload nut right in the center of the cover plate.

    Good Luck,
