If your car has seen a lot of sun in its day, be careful removing the rubber strip along the top of the windshield, called the welt. The plastic runner inside of it snapped in many places and looked very deformed when I reinstalled it over the headliner edge. I had to replace it. If I were to do this again on another car, I would try and leave the welt in place while removing and replacing the headliner. Just sayin.
