.8605 or .859 Reamer for a .860 Kingpin in a '60 Panel F-100

Gentlemen,
I've read post after post about kingpin repair and replacement and just taking it to a shop that knows what they are doing and let them do it, but I want to know the facts about how it is done properly.

I read in one post, a manual with no reference to what year truck, that it should "<!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves/> <w:TrackFormatting/> <w:PunctuationKerning/> <w:ValidateAgainstSchemas/> <w:SaveIfXMLInvalid>false</w:SaveIfXMLInvalid> <w:IgnoreMixedContent>false</w:IgnoreMixedContent> <w:AlwaysShowPlaceholderText>false</w:AlwaysShowPlaceholderText> <w

So my question is, for a .860 Kingpin in a 1960 F-100 Panel, what is the correct size reamer?

My other questions are, Is it OK if the shop I have uses a .859 reamer? Would I be better off supplying them with a .8605 reamer?

I guess overall, what should the final size of the bushing be if I am using a .860 Kingpin?

Thank you for time!

.859" reamer with .860" king pin = .001 too tight a fit. I use an adjustable reamer so the king pin slides through easily. According to what you wrote above, with a .860" king pin the bushings should be reamed to .861-.8615".
A good machine shop should have reamers to fit.
