David,
Starting in about 1977, that was how I set up my race cars. A friend of mine
built a jig to replace the threaded portion with smooth bore sleeves. We
retained the cotter pin system and used shims for side play adjustment.
This system worked just fine and only needed to be done once.

Subject: fulcrum pin engineering question
I do not understand why the fulcrum pin needs to be threaded at all? If
grease impregnated bushings were pressed into the A-arms and king pin, why
couldn't you use a hardened non-threaded pin, and allow free movement at all
three points in the outer assembly. A circlip could be used to keep the pin
from falling out, or fit a bolt to the narrow end.
