Issue with replacement rear glass :(

I had to replace the rear glass on my '21 M3 today, mobile install had it done in a little over an hour. But, the trunkflip seal is way out of spec. The glass is an aftermarket Fuyao. Can an OEM trunk flip seal be installed on the aftermarket glass?

I believe FUYAO is the OEM manufacturer.

Fuyao is the OEM for a large number of auto manufacturers in the world.

hi! so, problem solved, problem not solved. Trunk flip seal was incorrectly set by the installer - pulled up and over the trunk. I set it under and it is compressed properly. Second issue; they installed the earlier glass with the box grids, not horizontal....defogger doesnt work. They are removing the rear glass and Tesla is installing an OEM unit. That being said, my workorder from Tesla shows that the part number being used for the highland cars. Is tesla using the newer part?
