Cobra Trailer Part Needed

I am in the middle of converting my Cobra trailer tongue from the round tube (broken) to the newer square tube type and find I am missing a part. There is a rubber/plastic plug that goes in the rear end of the square tube to keep debris and small critters from getting inside the trailer box. W&W does not stock this plug. Anybody in the US got a spare one of these I could get quickly? Lots of this type of thing online but none look to be exactly the right thing.

Carve one out of a wood 2x4. Plus, I doubt any "critters" will make it past the damper mechanism. A couple of layers of Gorilla tape will also work.

I think I have this plug - I will check in the morning.

I do have it, but I now realize where it came from and have to use it!

This supplier carries them:

Yes, critters can get pass the damper mechanism. A field mouse can squeeze past some incredible small holes.

I use a bunch of stainless steel scrubbing pads stuffed into the tube. You can find them at nearly any store that sells kitchen cleaning supplies (big box, grocery stores, hardware, etc).
