This small clip finishes out the chrome molding that was originally installed on the windshield, side windows, and rear window of Vanagons at the factory.  These clips covers the ends of the chrome where they meet in the window seal.

There is one clip per window.

Note: some vans either did not come with molding or owners have deleted it.  Please check your particular van to see how many clips you might need.
