Does anyone know that this back window gasket is called and/or where to find it on a 2012 Mazda6. Its not on the window part its the back part of the window. I apologize for the poor description but I uploaded a picture here which hopefully helps. Its the gasket between the body and the small window piece. I've highlighted an outline of the gasket in red in the attached picture. Any guidance on its name, how to replace, or replacement parts would be so greatly appreciated! Thanks!
