Need w123 antenna mast
 

I'm working on my friend's 1984 300TD and the antenna mast is snapped off.

It's a Hirschmann 6000U 486 with a smooth mast, NOT the toothed type.

I see that Fastlane has them for $50, but I'd like to get a used one for cheap if anyone has one.

Here's the Fastlane link to what I need:
