open the sunroof about 5-6 inches. There are 5-6 clips holding the sunroof liner to the sunroof panel. Pull them down carefully. then slide the liner forward, it should disengage from the rear clips, which you can see in the pop-up position. You can either drill out the tiny rivets holding the panel to the slider rails, or remove the sunroof panel by the 6 torx bolts. You should be able to unclip the liner guiderails from the slider that is hidden in the roof of the car, near the back of the sunfoof openings. They're a pain to clip back on, but not too bad.
You have to adjust the sunroof when you put it back on.

Let me know if you want more info.

All,

I'm hoping that someone out there can tell me how I remove the Suroof Headliner piece from my car.

A yard that I went to today, had two 'nice' Sunroof Headliner pieces to choose from. I'd like to get one tomorrow and be able to do this without much fuss.

Can someone please explain how this is done.

Also.. on another interesting note, I'm gonna' go-ahead and perform a Bumper Lipo-Suction as well. I've finally got the "umph" in me to take a whack at it. I'll be sure to post pics once it's finished.

"Wish Me Luck!"
