I think he means the nuts, older style 10mm head with a concave like a lug nut. Fits ones without the vibration damper rubber on the ficm. A nut and washer will work just fine if your ficm bracket has studs, if not m8 bolts fit. There are 4 different ficm brackets that I know of on these trucks, so maybe take a pic of what you have, I'm sure I have several. As far as the clamps any shop who does any sort of diesel performance probably has some from old airboxes they have removed. I usually have several in my tool box I like to keep them for when trucks come in missing one. If you only have 2 put them on the back side of the filter housing it's the most important, the front 2 only hold the fender scoop on until you get new ones. Ford dealer should have both, I'm a parts hoarder...lol pm me if you can't get any elsewhere.
