The spindle/knuckle would have to be drilled/reamed to match the outer diameter of those bushings.
Maybe someone can find that post with the part number?
My observations have been that the bushings/pins get loose and eventually wallow out the spindles, while at the same time wallowing out the king-pin holes in the axle. Poor maintenance/inspections is the obvious cause of the often irreparable damage.
As stated above, over-sized king pins are readily available (sometimes in two over-sizes). Was this the thread you were thinking of? https://www.stovebolt.com/ubbthreads/ubbthreads.php/topics/977880/2.html
