I haven't pulled mine out yet, but from what I've read, the rubber moulding around the t-top openings on the inside of the car pull right out, and are not part of the sealing of the t-tops at all.
Pull those out, unscrew the light, and the visors, and I believe the headliner panel comes right out. Careful though, I've also heard of people snapping the board in half since it is so fragile in the center section.
