'59 1/2 ton Apache - Thrust Bearings

[hsdropout]

Anybody know if the thrust bearing replacement pieces go back together dry? or should a layer of grease be applied? I am assuming it eventually gets grease through the king pin zerks.
I have the originals so I can go back and see how the parts are layered however the kit came with 4 ultra thin shims, not sure where they are to go. There is also a fairly thick spacer (3/16", not in photo), not sure if it might be for earlier models? There is only room between steering knuckles for axle and thrust bearing
Thanks.
