On mine I drilled the bullbar to take a couple of shackles and then beefed up the bullbar to chassis mounting points with 2 x 5mm x 25mm MS Flat Sections (cut and welded to fit into the chassis), Drilled three holes in each plate, threaded same at 12mm and finished it off with 6 x 12mm HT Bolts and Nylock nuts. That bullbars going nowhere without the truck following!
