Good approach. When I get these wheels I will find the Kelsey Hayes PN/date code and all markings and report. Barry says he has seen 3, 4 and 6 clip wheels from back then. I have now noticed that also. Could be specific years or specific truck or just a vendors choice at the time. Further study and incoming verified info needed, as you say. As far as Cameo goes, I think the wheels have a set of nubs for full Cameo/Suburban Carrier caps. A universal wheel for dog dish or full. There are 16" wheels with 6 clips, 6 lugs and in the shapes shown. I don't know if you would call them GMC or Chevy or both. Source: Barry, Ebay, Jim Carter/Rob English.
