Heah guys already got the front bumper on and getting ready to cut slits in the fenders for the lower valence, but I got my rockers yesturday and they don't have the bolt in the back behind the door that goes through body panel to the back seat area...how should i bolt this up, i thought about getting either the factory setup from the old gfxs screwing them to the louver on the inside the the new gfxs so you can't see the screw from the outside but don't know if that will work yet any ideas...
