The bolts are self centering. There is a taper under the head. That taper aligns the K when you install it.
If the K is stripped of everything else, then it's just the four bolts. If not, the torsion bars need to come out and the upper ball joint needs to be separated from the spindles. If the steering column is still hooked up to the steering box, it will have to be disconnected as well.
