These plastic trim clips are ONE OF THE PARTS used to attach the front door card on the Ford C-Max. Each clip comes with the prefitted rubber sealing washers.
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.
