The kit is from Truck and Car Parts in Orange CA. Their part # 55-02403, page 22 of their catalog. 'Door Bumpers'
I believe I see the three spots for the bumpers. The flat one goes near the vent window, leading edge of the door, and contacts near the top, hinge side of the door frame. The other two conical ones go in holes in the rear of the door frame. The bigger one in the lower hole????
Maybe?
