King Pin Reamer Needed

[redmodelt]

People have been reaming the spindle bushings for years and years now we must hone them or all is lost! The spindle only turns a few degrees each way, it's not a shaft turning in the bushing. I'll just keep reaming them with original period reamers.
(My OP)If you don't have a stepped reamer then doing one side at a time is the way to go. If it's stepped then both bushing can be replaced then reamed.
