Holy crap Batman, I'll take a guess, for sure it's a Dana 300,at least the bracket and shifting parts are. The guess is, it's the elusive 300 from a IH Scout.
If your within 400 miles of central Illinois, I'll trade you for it. A Dana 20 AND, 304 core.
(2bbl intake, ).
I could up the offer if needed.
