What you should need is a 99-03 model v6 or gt hood .I think the 04 GT has the same hood as the 99-03s. Any way www.gefracing.com has them listed for $345
You also might want to give Saleen a call. They sell take offs. Heres their number
for availability and pricing
Hope that helps you, and welcome to the site.
