Alright guys, I was lucky enough to find someone who had some factory tow hooks for cheap, but they didn't come with the mounting hardware. I know if you buy them from the dealer they come with M bolts, but i haven't been able to find them anywhere. I want to use grade 8 bolts, but does anyone know if just 3 bolts will be enough? or does the m bolt do something special? Don't really know how else to mount them up.
