2016 F350 tow mirror - oops

So after years of backing down my driveway without incident, I clipped my mirror on the gate. The mirror still works but the plastic housing is cracked fairly bad. It is a power extending/ folding heated mirror and figured it was several hundred dollars to replace. Imagine my surprise when I called the dealer and was quoted just under $1600 including tax

I also checked amazon and google to see any internet options. I did find some but with questionable reviews. I am wondering if anyone here had this come up and find any reasonable options?

Thanks
