Trim piece removal on a 72 SE

[auxiliarytwin]

Hey all.  Below is a link to a trim piece that for the life of me I can't figure out how to remove.  It has no studs underneath that are fastened, so I am at a loss.  Any insight would be appreciated.

On the inside of the molding (window almost touches it) there is a flange. There are screws in this flange that hold it on. If I remember right, they may be hidden by the rubber wipe that keeps debris and some water from falling between the window and quarter panel. hope this helps....
