It wouldn't be too hard to make up the graphics, but getting them printed is a beast. Since alps stopped making the white print, decal printers are getting hard to find. I'd like to have one of these for myself, so if I can get a set or a good matching method, i can make one up for you. 04 donors aren't too hard to come by now.
There are decals available for both the 2003 regular car and the Marines car (only the hood is diffrent, I believe) but there are no decals available for the 04 car...an entire new set would need to be created.
Granted, most of the 03 sheet could be used, but the hood, decklid and the little outline mountains (which is what was normally on the decklid, IIRC) would need to be done from scratch, and the contingencys would need to be sourced elsewhere too.
