I can't find any instructions online or any pics I took but I am 95% sure after thinking about it that it is just a bolt. I seem to remember three nuts per bolt. One was copper or something. You have to double nut it first on the exhaust and then the final bolt keeps the rubber hanger on it. Does that make sense?
