The fender extensions bolt to the inner edge of the headlamp bucket and the other end attaches to the radiator support panel with 2 bolts. It may appear to be all part of the fender but they can be separated.
I have at least the the passenger side here in L.A./ Eagle Rock. It's still in the fender, but I could probably drill it out?! The fender was hit from the side, but that part is ok.
