While driving my '65 Notchback on a particularly winding road, I felt a small thud on my shoe. I continued driving without issue and later that day, I found this odd nut on the driver's side floor mat. It's M8 thread, thin at 4mm thick, and is a 13mm hex.

For the life of me, I can't think of what a nut like this would belong to under the dash, particularly under the driver-side of the dash. A brief look up under the dash confirmed my prejudice: the nut doesn't seem to belong to anything up there but it's a rat's nest of wires and shadows and pain and a kinked neck and blurred vision, so it's hard to tell.

Weirdly, ever since that nut appeared in my life, there has been a distinct rattle near/in/above the gauges and/or steering column when going over bumps.

Evidently, that skinny yet large-thread nut belonged to something up under the dash, but I'm stumped.

Can anybody solve this nutty mystery?

Radio mounting maybe?
Some early round relays screwed in to a threaded hole or maybe had a backing nut.

That was what I was thinking, since he mentioned it hitting his shoe. That's about the only thing I can think of that's that far back on the left side and could hit your foot while driving. There should be 2 nuts on each fresh air box. They originally were stamped sheet tin nuts, so someone might have replaced them (to replace the seal).

Usually, when your nuts drop on your feet it just means you're really old.

I believe that VWPieces has solved the mystery: locknut for fresh air levers!

I haven't torn into it yet to double-confirm (a bit of work for a single nut!), but the nut from his picture is a dead ringer and the fresh air lever is noticeably low on friction.

The nut must have landed on the radio and then jiggled over to the driver's side, fell, bounced off a few wires and made it to my foot.

Thanks guys for all the great ideas and helping solve this!

[Honorable mention goes to Tram Wink]

It's quite possible that's what happened. However, I'd contort myself into the foot well on my back with a bright flashlight (torch in the UK) and shine it up at the air box corners and verify both nuts are still on. It would just cost you the time to verify they're on there.
