Passenger side wing mirror assembly replacement

Hi, A bit of a strange one this! My wife was at the farm where she keeps her horse, when one got loose and bolted. It went past the side of the PHEV and almost took the whole wing mirror assembly off - the bracket has sheared, and the only thing keeping it on is the electric wire! We should be covered by the farms public liability insurance, but does anyone know how much repair/replacement might be, or where a replacement part might be sourced from other than a Mitsubishi main dealer. Thanks in advance.

Sorry should have added it's a 4HS, bought new April 2017

ebay is a good source. You may even get one in the right colour.

Just to add, they are the same as all Outlanders of a similar age not just the PHEV.
