check the Help! section of any auto parts store.. if they don't have anything in stock, ask if they have the Dorman catalog for you to look thru..
if you want to go in armed with part numbers, spend some time on www.dormanproducts.com and see what you can dig up.
i don't even know if Dorman makes this kind of thing, but maybe they will have another catalog at a decent parts store that might have what you need.
if nothing else, adel clamps are cheap and easy to find..
then find better stores.. every parts store around here has at least one full aisle of Help! stuff.. it's fun to just look thru it sometimes and see what looks like it might be useful..
