try out keystone. they have a hood that looks identical to the 03-04 cobra hood(they made the hood for the 3dcarbon "boy racer" sema car) i believe thats the hood in the very first link on the black stang.

trufibers hood is also in that link. they seem to be a decent company, making ram air hoods and carbon fiber splitters for gt500's
MRT has a new hood very similar to that as well, but it has some indentions in it, and isnt as smooth(you mentioned liking the smooth lines of the OEM hood)
