i didn't put shoulder in because i was total that is real hard, i instead put lap belts in, i haven't had any trouble and they keep me in the seat, shoulder is a better set up, it will keep your face from smacking the steering wheel grin

and i have a five window also, it might look bad having belts hanging in your corner glass, plus then belts hanging in the windows the kills the reason behind a five window - to see better
