F5 Duster

Yep, she's mine and thanks.
If you are looking at the US body stuff I think you are out of luck. They never made the duster hood and don't plan on it.
What viper hood are you wanting to do?
I'd just get a flat fiberglass Duster hood and then buy an newer charger SRT or viper hood off eBay and cut em up and graft them together.
