2015 Ford Fusion - I need a mirror

I’m Trying to get some parts to repair a drivers side mirror on my 2015 Fusion Titanium. I got a little too close the the side of my garage while backing into my parking spot. The outer part of the mirror scraped the wood trim on my garage. I’ve tried checking locally but both the dealer and a supplier can’t supply parts and say that I must buy the complete mirror at $700 plus installation! The parts I need are the black plastic trim around the outside and the turn signal indicator the is on the outer part of the mirror. Help!!!

Start calling salvage yards for the entire unit and paint it to match . Or contact a body shop to see if they have a solution.

Did they say why they had to install it?
