Is it your '95 E300 that you are talking about?
Look at Texasgeezer's post on Jan 16, 2018. He has pictures of the piece that he ordered.
It is one piece that goes from one side to the other glued to the bottom edge of the glass. They quite often break so it may have a piece missing and appear to be two pieces or maybe some of the aftermarket windshields don't have a proper channel.
