Welcome to Dr. Björn's Auto!
These are the mounting parts for the front upper grille of your T3 Vanagon. There is a small peg (which you turn to mount or remove the grille), a rubber washer and a clip mounted to the body. For you convenience you can see the parts in the drawing by matching the numbers in the listing. They are sold as single parts.
Note: To remove the grille you need to turn the peg a quarter turn with a flat screw driver.
