Stobin, I drilled & counter sunk trim screws in that trim piece at an equal distance across the trim piece & used the type of trim screws that are in just about every GM car on thee planet. They are the stainless with the beveled washer built or installed on them. It holds the piece up better & I think it looks better to have a bit of the stainless bits up there. For me it was very easy to put in & it really does hold them up better , & those clips are so temperamental & will either break or don't hold the piece in place very well as they get older.
