04 Cobra Vert quarter window seal replacement

Hey guys, just a quick question.
I've done a bunch of Google/ forum searching and I can't seem to find an answer.
Can the vertical seal be replaced on the 99-04 mustang verts or do I have to replace the whole quarter window? I know they can be done on the fox verts as I did them on my 91.
On my 04 Cobra there is a small chunk of the seal missing, doesn't really effect anything but it annoys me and I would like to replace it

Had that replaced under warranty on my o3 Cobra. This was 15 years ago, so I no longer remember what parts were involved but it was replaced

Thanks for the reply, doesn't seem to be much info on the net in regards to window or seal replacement.
None of the resto places carry the seals like they have for the foxbodys.
Guess I'll try my luck and see if I can find a clean used one.
