This is a list of our Universal Automotive Sideview Mirror Glass Plastic Backing Plate products, AKA Back Plate. This backing plate only fits the 85mm (3 11/32 inch) round dial mount found mainly on most European vehicles, but many US, Japanese, or Korean models that follow European parts design or have European original design roots also use this mount. Use the filter for various sizes, and also check the picture that shows the shape and size of the backing plate to find proper fit for your purpose. Contact us if you need further help.
