Anyone ever cut a vented "heat extractor" fiberglass hood?

Yeah it would require a flat hood if anything. I followed a thread where a guy took an SRT viper center section (like mine) and graft it onto a dart hood, ended up looking awesome. unfortunately photobucket ruined the thread so i only see small images of it.

My plans for my 72 Duster are to either graft a flat Duster fiberglass hood and a fiberglass viper style or fiberglass hellcat style hood
