Wing mirror glass

BL53

I got my driver side wing mirror bashed on my Aventura G600 LPA.  I think I'll get away with replacing only the glass and have asked the dealer and Pilote for price and delivery.  Bit of a nuisance with a coachbuilt as it's not a standard ducato part available
on the market.

Has anyone done this, is the mirror stuck on as per normal car/van?  Any alternative sources e.g. anyone know who makes Pilote mirrors!?
