I found this in the driveway when I started washing the silver sr5. I have a limited too and I have been swapping the trucks in the driveway. It is about 2 inches on the big side and 1.5 inches on the small side.
We got a feral cat fixed today. Tomorrow I am going to look underneath and at the fog lights. The part is whole and not torn. I dont see how it could be the CV boot.
I do have to take one to the dealer and will ask them if I cant see anything.
