I'm installing a Cargraphic free-flow cat and I'm missing 2 of the Aeroquip fasteners- They are larger in inside diameter then the standard ones for the rest of the exhaust- they have a 60mm ID. Anybody know where I can find some? or a supplier? I have been to the website for Aeroquip and most of the fittings they offer are all for fluid and oil, hydro hoses.. this I think is an aircraft fitting?? any help?

Thanks-

Coleman.
