Again all of this math. The real world is something different.

I did bolt on a set of late model wheels on my early model dana 60 no problems with the lug pattern but the offset stopped everything.

Late model GM or Dodge wheels still use the same old 8 on 6 1/2" bolt circle. Late model GM 8 lug wheels will bolt up and work no problem. The issue is with Ford wheels which are 8 on 170mm.

10 thousandths is not much in a 6.5 inch diameter space, but are late model truck wheels hub centric or lug centric?

That is almost 100 thou, or a 10th of an inch. That is a lot. Ford wheels will not work on a GM truck without some kind of modification as someone described above. GM truck wheels are all hub-centric, but any 8 lug wheel with the correct bolt circle will work regardless of center hole diameter (as long as the hole is bigger than the hub).
