    Called crossover because it pushes the passenger side knuckle from the driver's side steering box, so the draglink crosses over the axle. As opposed your ordinary push-pull steering in which the *driver's* side knuckle is pushed by the draglink, and when the driver's sidwe wheel goes up and down it changes the steering geometry significantly, 'cuz the draglink is so short. Lever arms and all that.

    Crossover gives you more resistance to the wheels' movement causing changes in geometry, and more force on the far side, I think. Someone will chime in with better words for this :D

    You will, in general, need a new draglink and steering box/arm, and some sort of hook up on the passenger knuckle.

    For D60's, this means arms:

    (I use ORD as a for instance, but there are other vendors)

    And on a D44 or 10-bolt you switch to the older D44 flat-top knuckles, etc:

    You'll also want, in our case (73-91 trucks) a 2WD steering box with fittings to match, or at least a matching (fixed/variable ratio) sector shaft, and then the stuff you see above.
