Ok. I think im following this now. Yes my kingpins are 1.109. I haevnt mearsured them yet but according to a data sheet that I found they are 1.109. I will measure before any work is done. So id like to summarize this and let me know if im correct or if I missed anything.

I'm starting with a 2 ton 59 gmc.

What I need to do:
Source p30 spindles, caliper and brackets, hubs/rotors and tie rod.
Ream the p30 kingpin busings to fit the OD of the 2 ton kingpin busings. Aprox..070. Press the p30 busings into the p30 spindle. Press the 2 ton bushing into the reamed p30 bushing. Narrow the p30 tiesrod. Assemble and enjoy.
