It's the trim strip labeled "6" here. And here you can see why I need one. No idea if it comes in any color besides black, but I need a black one.
Not ideal to buy used... Removing them will usually BREAK them...that is WHY they are usually replaced when new glass is installed... GET NEW CLIPS too!!
I know 100% the front one has clips...the rear not 100% sure..never had mine off..need to get one someday... E-MINI parts, AKA MINI of Bedford NH, the sister dealer of MINI of Peabody MA (where I got my car before they opened) has a discount off of list parts...one of the best around..I would check out their $ and even inquire about the clip vs tape info....they also happen to be a sponsor here!! SO win win!
Zippy we are talking about the rear C pillar not the windshield A pillar. No clips need at all on the B and C pillar ones. Its just double sided tape. Only clips on the A pillar.
