1965 Barracuda bumper jack base, spring, wing nut, etc

I might have not been as clear as I should have been - this jack with it’s base DOES NOT fit any SBP wheel. It’s probably from a 73-76

This jack’s base DOES FIT the center hole of a SBP wheel. The center hole of the SBP wheel is the same whether 13 or 14 inch
