the opening on the brakes ducts are larger than the opening on the bumper part. there is a lip on the bumper for it to slip around. it's a pressure fit between the bumper and the inner fenderwell. you can go out to yours now and push them back and they will fall out of place.
on the ts bumper, the screens screw onto the bumper and the duct will sit over them. are then needed on a street car, no.
