Toyvo,
The king pin bosses in my axle are good, they don’t need re-sizing. The bushings in the knuckle are brass and will yield quite easily to a straight flute adjustable hand reamer, you should only have to remove a few thousands of an inch to line up the axis and bring them out to size. That’s the way it was done in most of the Chevy garages back in the day, I was a parts manager for Chevy for five years back in the late 50’s and 60’s and king pins were a common front end problem.
I’m really surprised that KD or Snap-On don’t still sell king pin reamers.
