The Mysterious Plastic Trim

It frustrates me I cannot seem to find any replacement - OEM or reproduction - for the plastic trim behind the rear seat of a tintop. Not even ETKA has a part no. nor a description. It's under the "roof and pillar lining" section though. 

It means that it is NLA for no part number, if you can't find one stamped or etched in to yours.  

I am really mad that I lost my ETKA from 10 years ago due to a puter failure…..as it had all the part numbers back to 76

Unfortunately not even a VW/Audi stamp on the inside. Thought they liked their logo added on every nut and bolt.  

Only thing I can add is to have them scanned in to a 3d rendering then printed.
