This is an older style of interior trim clip used by Fiat Group. The small white clips were normally used for door cards and interior trim panels. They were used on the Alfa 33, Lancia Thema, Fiat 126, 127, Regato, Ritma and Uno. They are not the only clip used on any of these models so please check the measurements and compare the photo before you order.
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.
