WTB - Headlamp Component

[Lean Machine]

I'm not sure how this was broken, but I need to replace a small component of my left front headlamp on my 2005 Hummer H2. See the component circled in red on the picture. Doesn't look like this is sold separately and I don't need the whole head lamp assy. Anyone happen to have this piece lying around?

If no one has any you can usually find pretty beat up headlight housings on ebay for dirt cheap. See if one of those has the retaining nut and buy the entire thing.
