Definitely not any FoMoCo, In thinking odd Ball Independent Manufacture. The reason I say this is the Long holes for mounting Fender, & the top Fender bead. You might make a list, say 20 Independent manufacture Makers. An then get only Google & Check the out Individually ex. Studebaker Image. Go thru your List. Hope this Helps.

Looks like rear tourer dodge or overland or something equally dull. Sent from my SM-G930F using The H.A.M.B. mobile app
Looks a lot like the ones on my 1922 dodge touring rear. Mine are so mangled I can't be positive, but yours looks mighty close.
