Steve,
The adapters I'm talking about are nothing like what you have on your C10.
As you may or may not know Dayton Wheels are just open center wheels that are designed to clamp onto Cast Spoke Hubs. These adapters are cast iron and the center has your 6-lug Budd bolt pattern with clamps on the outer part of the disc to bolt/clamp the Dayton Wheel.
These adapters were used by fleet owners that ran Dayton wheels on the entire fleet...if they had gotten a Budd wheeled truck for some reason they would add the adapters to it making that truck now a Dayton wheel truck to "standardized" the fleet.
I'll try to take a picture of what I'm talking about if Spanky doesn't beat me to it...
