Discontinued 04 mustang RH fender apron

Does anyone know if 98 RH fender apron work on an 04 GT? The 04 has been discontinued and I want to avoid buying one from a salvage yard. I would think the only difference would be maybe some of the holes for Air filter and wiring harness, is this the correct assumption?
 
Check around with your local parts stores to see if any of them can order through Keystone. Keystone is a source for aftermarket reproduction colliision parts.
