funny i just did my king pins on my truck yesterday, what i did was use the old king pin and hit the plug so it wedges in the spindle hole holding it tight,there are not to be flat but just enough to tighten then in the spindle,be sure to ware eye protection when doing this too.its the same thing you would do on a freeze plug on the side of a block as long as its a flat type of freeze plug, hammering them flat is how you can take them out, i think they should be 11/16 flat plugs if you have a .922 pin. i would think some parts house should have them or at least they could order them for you.
