Air box bolt needed

[Tattooboy]

If anyone out there has done away with their standard Monaro VXR air box, does anyone have a spare bolt I could have/buy?? Had to take my air box off to fit HID's over the weekend and managed to loose a bolt in the engine bay somewhere !! Have had the bottom tray off but it wasn't sitting in there. It's one of the bolts that holds it onto the body, not one of the 3 screws to take the top off. many thanks in advance.
