These are not full floating king pins. The king pins are rigidly
held in the axle and the spindles are bushed. You could press
them in your self but you're better off taking them to a
machine shop to get them honed. It would be expensive buy a
reamer long enough to achieve the line bore required and even
then, honing will give you a much better fit.
