Have heard that the fiberglass hoods have one problem. The trim ring does not have a definition line to separate it from the hood. It all looks like one piece. I also have the name of a guy who takes the standard flat hood and adds all the substructure to the underside, spot welds it into place and his trim ring is separate--like original. Looks REAL good--got one on my Challenger 440 Six-Pack and I like it!
