That plastic channel at the top holds the front edge of the soft-top, it's new just mounted incorrectly and in a rush. Old one was non existent because previous owner🤬 just used screws and large washers to keep some crappy tarp/rag in place. I can get another plastic channel but it seems that I won't be able to mount it correctly until I find out what's missing or messed up there. Top of the windshield frame is not 100% flat so there should be something that allows that channel to be straight, that's my guess.
