Hi,
I have found the source of a leak on my 1999 z3 2.3, and I am struggling to find the correct part number for a replacement part.

The seal between the triangular fixed window and the main side window has a small tear on both sides, which looks like this

I can't figure out where to find this seal. The closest part I can find would be 51328410161, which is the entire triangular fixed glass piece, including the seal. I cannot find the seal on it's own. Is there any way to replace just this seal, or fix it some other way?

Thank you for any advice you might have.
