Antenna sloted nut

[Saturnin15]

I'm looking for the small round nut that holds the antenna at the bezel.

Thank you

In an effort to narrow it down, what year and what car?

Is it for power or manual antenna?   
Try Fusick, cad parts ltd, or the other million used parts dealers.   "Cad Tim" might be/have a source.
You might find a universal replacement that fits at the parts stores.   You just have to search these small parts and check around.   It's not a big sale, so doesn't draw interest.
