Not a difficult job.
You can do the disassembly and fit new bushings in the spindle.
Then can have bushings honed at most any automotive machine shop. Alternatively they can use an adjustable reamer with a pilot, you can find one and do it yourself, or a traditional machine shop may have this type reamer with pilot.

The goal is to have each bushing reamed exactly to size to fit kingpin snugly and also so they share centerline. The piloted reamer or long hone helps achieve the same centerline.
