Hi all, there is a piece of weatherstripping that runs up the A pillar, along the roofline, then down the C pillar. It appears to help seal the doors from water runoff. Does anyone know what this is called, what the part number might, be and where to source a replacement? Thanks

 

I found it:

20789463 Front and Rear Driver Side Door Upper Auxiliary Weatherstrip
20789464 Passenger Side Center Pillar Upper Auxiliary Weatherstrip
