Hello:
Do yourself a favor and forget about "Unlimited". Seems these guys keep getting horible press and still turnout (limited to choice of words on familysite Just insert a bad word here)
I bought one of their lift off hoods with a hemi scoop on it. I spent more time and work on that piece of crap then i care to admit to. Inadquate bracing, fiberglass to thin where I needed to install my fastners. I had to add bracing because the hood bowed upward so badly even at lower speeds 75mph and up.
Take ProStDodge's advice and dump "Unlimited".
