I've read the explination here but it's pretty vauge:

I've got everything disconnected but I can't figure out how to release the clips at the back window. Are the clips that pull straight down, or does the headliner slide forward or backward to release them?

The article says to put your fingers under the headliner and pull down, but I don't want to pull too hard and break somthing.

Can someone give me some instruction here? What about around the sunroof, how does it release from there? (not the sunroof itself, just the headliner board)
