FYI for anyone with an e36 hardtop. I decided to replace the black trim parts on the side of the hardtop roof parts when I’m getting it sprayed as mine are chipped.
It’s the black piece circled below in yellow. The left hand side ones are now NLA in Europe and the right hand side ones are now on back order.
In case anyone is looking for some there’s 4 of the left ones and 2 right ones left in dealer stock in the US.
Part numbers are 51138165045 & 51138165046.
https://www.bmwdirectparts.com can get them as they’re a dealer in Nebraska.
