    Will a 1980 14 bolt fit under a 78 pu with a 12 bolt? Any major concerns?
    Thank you.

    Save 33" tires? wtf does that mean?

    1 ton 14bolts have spring perches and shock mounts at different distances , so you hafta move those.

    3/4 ton 14bolts are direct bolt in.

    Van 14bolts are longer (not sure about spring perches) so the axle is just as long as the front unlike in any other axle.

    It is relly easy and pretty much bolt in. you'll need a new Ujoint at the driveshaft too, i believe it's called a 1350.

    *sigh*

    the srping pearches will have to be rewelded, possible shock mounts also.

    you will need a conversion u-joint.

    the rear will be 8Lug the front 6Lug, so you will need to convert either the front or the rear. the fronts will need 8 lug conversion pieces from a 3/4 rig, the rear an adapter such as the one from Echobit.

    e-brake will work, but you might have to work the cables a bit. brake lines will also swap.

    Width will be the same, but will still be 1.5" narrower on each side than the front, unless yo get a Van 14BFF.

    that is all.

    zakk, when you do your respond to some of these questions save them on your comp so you can just do the blanket answer to some of the common ones we see asked a lot...

    jhodge, if you do the change over you either need to move your leaf pads or buy new ones and weld them on ($45-$50 for the new pads) ,
    12 bolts have 6 lugs rims and 14 bolts have 8 lugs, you can either convert the 14 bolt to 6 lug (spacer rings and hub work $275-$325) or buy new rims( 15”steel rims$200-$250, remove and re- mount tires$80) and convert the front ($100)
    convert the 14 bolt to 6 lug = $300.00 ref
    new rims and convert front to 8 lug = $400.00 ref
