sharks tooth grille on 72 duster.

I bought my 72 duster rolling chassis all taken apart but two sharks tooth grills came with it. I am pretty sure this is not the grill that came off the car and i dont have any of the mounting hardware for it. If someone can snap some pics that would be awsome otherwise if someone can give me a link to what the parts i need to mount look like so I atleast know if im buying what i need or not. Theres two tabs that line up with holes on the top of the grill and the passanger side of mine is broken off. Any help is greatly appreciated.
Thanks,
Joe
