Fiat Ducato wing mirror outer casing replace

To replace a Fiat Ducato wing mirror outer casing, you'll need to identify if you have a short or long arm mirror, then carefully pry off the old cover (often from the bottom or top) to access the internal bolts, typically using a plastic trim tool and a T40 Torx bit, before unhooking the electrical connector and unbolting the entire mirror assembly to fit the new, pre-painted or paintable casing by reversing the steps, securing with clips and bolts.
