go to a local automotive paint store and buy panel adhesive. it is a two part adhesive. you might have to buy the gun for it but it wouldnt be to expensive. for the gun and adhesive it might run you 60 but well worth it. i molded my front kit to my car and it works awsome. it bridged the gap perfeclty. just remember to put enough in there, let it dry over night or atleast for 6 hours. sand and apply bondo.
