Replacement part

Yesterday I was getting into my car and had left the sunglasses holder thing open. Me being the idiot I am, I hit my head on it and broke one of the arms that holds it up. I have a sunglasses holder clip on the visor and am using that for the time being and keeping the thing closed. I could probably super glue it, but I'd rather get a replacement part. Anyone know what the part # for it would be and where I could find it?

Thanks
