The liner is also wrapped into the windshield and rear window openings. You need to pull these to do it right, particularly if you want to try to re-use it. This might be the one time I recommend SOR...get their after market new one. Gives you more material to work with and you do not need to try and save the old liner. Pay attention to the details, use 3m adhesive and it helps to have extra clips on hand.
Well, they did 4 years ago...
