King pin slop/play 1967 c50

[CarolinaHD]

According to the man I bought it from, their mechanic rebuilt/replaced alot of brake parts in 2004 right before he died.(which is why the truck sat for so long they had no one to work on it).
Best I can figure is there was a little slop and he thought replacing the factory bronze bushings with the cheap Moog plastic parts would tighten it up? I'm sure it did for about a week lol.
