I was looking for the part number but could not find it I just told them I wanted a 2.5 " band clamp or some people call it a strap band clamp. The one I got was the same length as the ford clamp just didnt have the alignment notch which you dont need. when i cut my rear bumper i used a dremel and a cut bit from homedepot, but I know people have used everything from an x-acto to tin snips. It cuts really easy, plus if you mess up all the more reason to buy that cali special rear bumper. I have the FRPP exhaust cut out covers on mine.
