i've got my tahoe limited bumper in paint right now and i cant figure out the fog light situation. i still need to find a factory switch and figure out the wiring, but i already purchased the fog lights themselves through lmc truck. now what i cant figure out is how they mount to the bumper! looking at pics online, it seems like theres a black housing or light bucket the unit sits in. lmc truck doesnt apparently carry this piece and i cant find it anywhere. also, the fogs are way smaller than i thought they would be (i double checked the part #'s and they are correct). any help with info or pics is appreciated!
