Just got back this morning from picking up the wheel adapters, about 1,600 miles in 33 hours total time, glad there were two of us driving.
Here are a few fresh pictures of them:

Click the little one, and then more will follow.

Cast in the inside of all 4 is "DAYTON" so my guess is Dayton made them to fit the AD Chevy trucks so they could sell their own brand of rims? Where some of the other adapters as used on GMC trucks have a GM part number, or perhaps Dayton made those too, and GM stocked and sold them?
