A chunk of hail took out my passenger side convex mirror on my tow mirror.
The small convex trapezoidal-shaped insert piece. Is there any place to find one of those without buying a whole new tow mirror? All I can find seperately are the main large flat mirrors.

I haven't tried the dealer, just because.

 

I just had to replace the big mirror, dealer part ~$38. I'd give them a call. You will need your vin.

Good luck.

 

got mine at a local windshield repair shop,around $35.00 hope this helps!
