Will this Rubber Washer fit my 1985 Vanagon or Westfalia?

Yes, this Rubber Washer is designed specifically for all years and models of the Vanagon, including your 1985 Westfalia. It's made to fit the upper grille pin fastener used on these vehicles.

How many Rubber Washers do I need for a complete grille reinstallation?

Each grille pin fastener requires one Rubber Washer. Since a standard Vanagon upper grille uses four pin fasteners, you’ll need four washers for a full replacement. Be sure to check your current fasteners to confirm the number needed.

Does this Rubber Washer come with the pin fastener, or do I need to buy that separately?

This item is just the Rubber Washer itself; the pin fastener is not included. If your pin fasteners are also worn or missing, you'll want to order them separately to ensure a secure and rattle-free grille installation.
