Are these original MoParts or not?

http://kuvablogi.com/nayta/3160630/ and next three

I have one complete set and one set w/o bars. Those are for 7,25 rear only... Old stock from company, which imported Mopars to Finland in 60´s and 70´s. One story is, that those were for early Valiants and Barracudas raced and rallyed in late 60´s.

Rear braces and bars ends are cast.

In rear bracket casting is FMW 52-54 and in both bar end castings is M-1. No pentastars or other easy markings...
