Leer rear glass weatherstrip

I bought a used Leer 100r and the weatherstrip that rests against the tailgate is wavy like the ocean. I know it still functions fine but it's bothering me. I've searched all over and can't seem to find where to get a replacement and also if a new one is going to be the same way. Does anyone have any insight on this? Thank you

 

No idea, but free bump because I could use one as well. Never really took the time to look for one, but I'd assume some sort of generic weatherstripping roll from Amazon could probably do the trick. Now which one? I have no clue.

There’s probably other places to buy them. That’s just the first one that popped up for me “Skirt” is the keyword to search
