Anyone know where this nut goes in the CB750 K7 airbox?

Part 15 on this diagram:


Is apparently:



But I'm missing them. Anyone know where they go? I put the airbox together, and don't see an obvious place to put it, even with the part diagram. I'm asking so I can see what will fit at the hardware store. Thanks!

Ihave a k8. Airbox appears to be the same. I'll check tomorrow morning since I already have the box off anyway.

 I think it's a stop nut for the thru bolt. it keeps you from over tightening and crushing the air box. But I might be wrong. The description is cover nut and the bottom is the cover.
 I use double nuts on the K0 airboxes to accomplish the same thing.

Correct. It also holds part number 12 to the upper half of the airbox.

Here's a writeup I did regarding disassembly of the airbox:
