These 6mm clips fit a number of different Subaru cars and many other models. They will fit most rubber weatherstrips where the bodywork hole size is 6mm. The large head of the clip fits into the hole on the rubber seal and then the clip is clicked into place on the bodywork.
Please check the details carefully before you order. Every vehicle has many different clips and fasteners. Even if the ebay compatibility check says these are used on your vehicle, that does not mean that they are the only clip and will be the ones that you need. It is important to check the photo, part number and dimensions before you order.
