Rusty Heaps - I didn't check before posting my reply above, but after your prompt, the pictures below show what my 25th Anniversary Edition Hollander's Interchange Manual indicates.
The only addition I'd make on earlier info is to include the '41-50 GMC 1/2 tons as also being a source, as they used the same spindles as the Chevy.
