Windshield wiper nut cover?

[Mississippi]

I have lost the black plastic cover over the nut which attaches the wiper arm to the coach. Does anyone know if you can just purchase this part. I know it comes with a new wiper arm assembly, but that is an expensive solution to a very simple issue. I already carry extra arms due to my experience with the arms breaking under heavy use. Is there a part number or a good description for what I am looking for?
Thanks

Check your local hardware departments specialty fastener section.
Look for a "castle nut".

It's not a castle nut, it's a flat-topped, cylindrical cap... I'm missing one also. It fact, several months ago I found a little black cap (what I now know was the cap) in the street in front of the house. I knew it was a cap for something so I picked it up and put it somewhere that I have never found again... I always keep those little things that I find, but have trouble finding them again when I find out where they go...

On a 2008 Dutchstar, it is a fairly large black plastic part that covers the nut and the lower part of the wiper arm. It is about 2" long and snaps on where the wiper arm folds back.

OK, that must be different than the 2000 DSDP, mine is about 3/8" in diameter (flat-topped, cylindrical cap).

Here are a few Googled all kinds.

Newmar Parts Dept. came through again. Emailed inquiry to them late yesterday and got a reply this morning including a picture of the part. Got a supply of them ordered this morning and should have them by the middle of next week. Thanks to the guys in the parts department.
