The bolts that came with mine are M12's Some of them go into nuts welded to the frame at the factory and others have to be drilled and installed with a separate nut. The nuts have long tabs (5-6" long) on them because there are places where you can not get to with a wrench.
I got my hitch from U-Haul and its the round tube type. Your square design may be different as far as how its installed, but the bolts should be the same. I suggest that you head to a hardware or auto parts store, explain what your doing and ask them to help you find the right ones. They may have the entire kit at NAPA which would include those tabbed nuts.
