I have a 2008 Saab 9-3 Aero. The sunroof has two arms that serve to push the wind deflector down when the glass slides toward closing. Each arm has a "T" shaped pivot pin that fits through an oval shaped grommet that snaps into an oval shaped hole on each side of the wind deflector. These grommets are not detailed in the Saab parts manual's exploded view, but are very necessary to keep the arms perpendicular to the surface of the roof as they pivot to push the wind defector down as the sunroof closes. My sunroof is missing one of the grommets. Does anyone know where I can obtain this part?
