    When I go to the local pick a part how would I tell if the "new" steering box is good or not? Also what years of box should I be looking for? I have a 78k5.

    Is there an upgrade year or model? I heard that there is one called an 808? /forums/images/graemlins/crazy.gif? that would have a 76 cast somewhere on the housing that is supposed to be an upgrade. Any truth to this?

    thnx

    First off I bet you will have a much harder time finding a 4wd box but they will probably have a few. In 79' or 80' GM wen't to a different style fitting thatn the earlier ones. They are the same boxes though far as I know. When you find a 4wd box look at the fittings and if the holes are deep than it's the early style, if the holes aren't deep than it's the later flare nut style. As far as picking one that is "good", well I picked one out, looked it over and tried to see if it had signs of leakage during use, otherwise it is a guessing game. I was lucky enough that I got one that didn't leak but with big tires it doesn't take long and they are leaking. My "new" box is starting to leak after only being in use on my truck for about 5 months.

    You can't change the fittings. If you wan't a later box than you will have to convert the whole system over. It will take a later box, pump, and lines. I would just find an earlier box like yours.

    flared are before '80 and O-ring new design are '80-up, you can take a box off a late 68 and through 79, blazer burb pickup, 1 ton, etc and is same as your 78 k5 box(p/s)

    boxes in yards would be hit and miss, some worn out and some not, just like on the streets, some worn and some not.


    good luck

    I've seen posts of adapter pieces that screw in to convert one to the other, but I don't recall the specifics. You can also get lines made at NAPA or similar with o-ring at one end and flare at the other. Also, the fitting on the pump does screw out and I'm pretty sure they interchange. So, you could just swap the fitting on the pump if you need to use the "other" style box...

    I trashed a pump once due to that whole '80 switch over. I got a new HP line for an '80 it screwed in too far an ruinded the pump. My truck is an '80 by title and vin, but every part I have gotten since is for a '79. The vin is the short one from pre '80 rigs but comes up as an '80. Anybody else have that problem

    Like we said, you just have to kind of guess. You can try turning the shaft to feel it and look for leaks but otherwise it's a total guess.

    Baddog, you are correct. The fittings interchange between flared and o-ring PS boxes all day long.
