id rather have a steel one, at least on our trucks, since they are trucks and we drive them everyday, the steel would last a long time, the fiberglass would be nice for weight savings, but on trucks as heavy as these, i dont think it really helps much haha, besides fiberglass never really fits right, my stepdads got a 71 oldsmobile cutlass with a fiberglass 442 hood and the lines arent right on it, its definitely light though for as big of a hood as it is
