There are a constant flow of GT scoop "take offs" on eBay. So, you might be able to easily find one in the right color there.
The GT scoop fits onto a regular '96-'02 V6 hood ('03 and '04 V6 models use a different hood (the '99/'01 Cobra hood)). So, it should not be very hard to just drill the required screw holes onto your existing hood.
