Once the weatherstip is out of the way you can easily access the retaining screws. I assume the weatherstrip is all you buy when you replace it. Just sticks back on to the chrome strip. It also has a thin piece of foam between it & the cars roof. It too needs to be replaced. I have been checking on parts as I remove stuff to make sure is avaliable. Did not check on this so I hope someone sells a good replacement.
