16'' Six Lug 4 nub Steelies ?

[Ironhorse]

Lately have been seeing reference to such on the board for those wanting to run a tall and skinny 16'' tire and stock hub caps. Specifically, what vehicles and what year range did these wheels come from? Am familiar with our truck 15s'' (5 and 6 lug) and 16.5'' wheels (8 lug) just not the 16s'' Will be going to a fairly decent swap meet within couple weeks and would like to be prepared to the possibility of finding some. Besides the newer Toyota trucks and Jeeps isn't GM the only other mfg. to use a six lug wheel? Those that know, please share some knowledge, LOL. Always like to learn about these trucks.
