rear windshield mounted ballstuds

New owner of a 2002 Liberty. I need both rear windshield mounted ballstuds as one is broke and the other is barely hanging on.

I have searched the web and cannot find this part listed anywhere. Does anyone have any info on this particular part? I would imagine others have had this part brake and need replacing. Please tell me its not a part that i can only get with a new windshield! Any help would be greatly appreciated
