Help on hardtop for tj back glass molding

[appforest]

I have recently bought a used jeep tj hardtop for my 2004 jeep wrangler. Upon inspection closely i found the back peice of bottom trim for the rear glass is broken and missing. It is the piece of plastic with rubber trim that is glued onto the bottom of the rear glass of a factory hardtop to seal off when you shut the back door. I have been trying to order the piece from a jeep dealership but no one can produce the item. Can anyone help possibly find a part number or know if this piece can be purchased seperately. The dealer got a part number for the rubber trim on the plastic piece but that is all. The dealer acted like i would have to buy a whole new back glass. If anyone has a damaged hardtop with that piece i would be interested. Any help would be appreciated thanks guys.
