I've purchased a zunsport grille,says it should be straight foward fit just screws in.in the instructions it says screw in the screws to the brackets and job done,now I have no brackets for it to screw into.when looking closer I notice I could remove a plastic section and behind there is a metal ring.im now wandering if that ring is the towing eye and if I have bought the wrong grille,can anyone help and if someone with the towing eye grille can tell me if it comes with brackets
