I recall those adapters now, thanks for the links.

to quote the blog
"These are off the rear wheels of the bus. They fit over the 8 lug one ton hub and provide an offset for the budd wheels. Note that these adapters fit the 8 lug hub and convert to a six lug wheel. The Stemco Model number is TD924. These were used primarily on school buses and wreckers. The allowed the body to be set on a one ton chassis which was usually narrower than a 1.5 ton or 2 ton or larger. "

Does that answer the question?
