Euro Mirror - Broken Support

Someone broke the internal support of my mirror trying to walk by my car. It's a small metal part that holds the mirror in its adjusted position using a spring for tension. Unfortunately I don't see it on the parts diagram because it's internal to the mirror (and I assume came to the factory as part of an assembled unit). The piece snapped where there is a high-stress 90 degree joint in the cast, so I'm not confident it could be repaired to acceptable strength.

Does anyone know if there are sources for this kind of thing? Has anyone used a metal fabrication shop that could print or cast one for me?

 

Very close, but I failed to mention mine is a 308. I'll look though in case they are close enough to work.

 

Can't tell you how much I appreciate the help. I was considering using my 3D printer to duplicate the part and having someone cast it.

My wife (the mysterious person who broke the mirror when she was getting something from the garage) thanks you as well.
