I want to move my rear turn signals but, I don't want to leave a gaping hole in the fender. Does anyone know where to look for a cover or reflector I can stick in the hole where the stocks stick out?

 

They mount on the fender support, not on the fender, so you wont even see the whole in the fender. And you can get plugs for them, but If I remember right, there is an imprint where you will pull off the turn signal stand off, and you will have a hard time hiding that.

 

I had this same issue when I relocated my rear turn signals. You can pick up hole plugs at the dealer. The plugs are offered in chrome and rubber.
Chrome plug - P/N 53377-04 $5.00
Rubber plug - P/N 68446-00 $0.95
