Quarter Panel Extension is a body-side fitting on the Mazda — small, inexpensive, and usually the reason a larger panel will not sit flush. Genuine Mazda part number b4ya7040x.
Once the fitting fails the surrounding parts work loose and start to chafe, so replacing the small part early prevents damage to the panel it holds. Match by part number — body hardware is dimension-critical and a 1 mm difference in shank or reach is enough to stop it seating.
Order the surrounding clips at the same time, since the originals generally break when the panel is removed.
Panels & Extensions Quarter Panel Extension replacement for Mazda. Cross-check the part number against the component you are removing before ordering.
