I need to poke my head under a normal 370 rear bumper. Since I have the Nismo version and my plate is technically "illegal" my rear end doesnt qualify....LOL. *hint* that answers your last question.
Seriously though, more than likely I can pop my head into the Nissan dealership and take a look. Honestly I havent seen many 370's with that type of mounting plate on the underside location.
Hence that was my worry that you might need a rivet gun. If there was a hole under there you could run some lock nuts and attach the plate there.
The brackets at Rons were located by the cashiers desk area behind of them. That store is pretty sparse since they bring in most of the items versus stocking them. If you know someone that can bend stainless steel straight and evenly, just have one made for yourself. For a little piece of metal...its expensive in my opinion...but I am lazy so I just bought one.
