Installing A-Pillar trim without busting it

Are there clips because that sucker is tight. I was afraid I was going to break it.

Yeah it has a lip about 3/16 long that hooks under the weatherstrip channel but will twist a little and pull down. There are clips inside this metal trim, one near every headliner seam. They bite pretty good but if you'll grab it with two hands from inside and give it a firm yank, it'll come down.
