Something doesn't add up there. Your old kingpin OD is 10thou larger than your old bushing ID.
That aside, if the new bushing OD is correct for the spindle ID what would the reason be to ream it for oversized bushings?
The service manual for the 58 said to press the new bushings in with two thumbs (lubricated with lard) and if they were loose/fell out then ream the spindle for oversized bushings.
I don't see any indication that you have an issue?
Edit: is it possible that you are measuring the dirty surface of the old kingpin and that is affecting your measurement?
