I had my King Pins re-done on my at-the-time 1946 One Ton Pick Up, back in 1979.
Anyway, the place I took it to was a bunch of old skinny chain-smoking guys who had been doing front end stuff since the 1940s.
They took the Axel ends apart, heated the King Pin 'Eye' ends to a good Cherry 'red', Dollied them 'in' all round, then once cool, reemed the Holes, and put the new King Pins in.
Turned out perfect!
I put over 400,000 miles on them afteward and they were still excellent and snug ( I always Lubed every 2,000 miles or sooner ).
Initially mine were wallowed pretty bad and past what the available 'oversize' would correct.
Plus, when wallowed, they are no longer 'round' inside and will need to be at least reemed, and to have over-over-size pins ( which one can make or have made if need be )...or, one heats and Dollies it all in and then reems for standard or as one pleases.
