Can make up some new ones easy enough using sheet metal, usually the main big inner flat part of the bumper is there, so just do as I did and through bolt with SS nut and bolt, this will be needed and cut to size, file down the edge of the support part around the hole and you can then hold a nut there between the outer bumper rear face and the flat section of the support, whilst putting a bolt through from engine side to bumper direction, I'll piccie mine when I get me new one sprayed, as lot easier to show than describe.
