    I know, this has been covered, but I am a dumass when it comes to search.
    I have a lione on a mid 70s K30 dually with a blown motor. I am thinking about installing the axles under my 70 K5. I realize that driveshaft mods are required, what about the pads on the axles??? Also, will my manual steer idler arm work? Trying to get an idea cost wise what this will cost me.:confused:

    if 1-ton then should bolt in. rear will require a 1350 conversion joint. if 3/4 ton rear then spring pads will need to be moved. Also make sure it is a 60. They didn't start putting them in till 76 right?

    Front will need a hub conversion.
    It'll be to wide unless you want to run the dually front wheels.

    OR - a set of 'not' recentered H1 wheels.

    oh, didn't notice dually. You can also machine the hub back to single whel but I would run h1 rims like Mike does

    i'll be running DRW 60/70 combo from an 80s K30. and let me tell you one thing, it's wide. with my boggers, stock H1 wheels, and DRW, the front measures in at about 96". talk about full size.

    Not to hijack, but what axle did they use before the D60 rear for dually's? I know they used the Eaton 1-ton, but I've never seen a dually version of it.

    There wer different versions of the Eaton. I believe 52 was the 3/4 ton version, then came 72 for 1 tons, and 110 for even heavier trucks.

    I can testify to the fact the Burro made it within 200 yards of Engineer's pass summit with no front hub engagement in the middle of winter.

    Any man that can run OCG with a stock 70 Blazer, wire hoop steering, and a column shifted clutch will remain in the record books for eternity.

    :D


    Hey, if I remember correctly the Cherry Bomb was busy with a minor steering issue. :haha: :haha: :haha:

    Nebraska looking for D60's
    Back to the topic. I used a 80' Dually D60 in my 67' and it was bolt in. I swapped the hubs out though cause I wanted SRW. A D70HD is direct bolt in and a 14bolt out of a 1ton is too. There are dually Eatons. I've seen quite a few. They are 63" WMS like the early ones. The mid' 60's up were 65" WMS and the Van/Box Truck ones were 70" WMS. I've had/have all of them. I personally would sell the dually diff and run an Eaton if you can find one cause they offer more clearance and are cooler :D .
