I just bought two Warbird style hoods from this guy, and man, was I impressed! The Warbird replicates the look of the 98-02 WS6 hoods (openings and bulges are factory dimensions!) and they do it well. He even included factory grills and new hardware. The guy's name is Roger, and he frequently sells his made-per order hoods on ebay. The best thing is that they work with factory WS6 Ram Air ducting and Air Boxes.
If you've thought about buying a hood from steelhoods.com (they're nostrills have to be cut open and don't provide for Ram Air) I STRONGLY urge you to check out these hoods. Like I said he always sells them on ebay. He even told me he pokes his head in these forums every now and then .
