I realized I had lost one of the screws that hold the airbox in place. It is holdin fine with just one but would like to secure it properly. Trouble is, where do I find this part or does anyone happen to have an airbox that is unused and has this piece that I could buy?

 

I don't know the screw you speak of, but if it's just a normal screw, take the other one to Home Depot or Lowe's and start matching them up.

Or, stealership?
