I'm going through the same thing and decided on two avenues.
I was lucky enough to find a 97 at a dealer and took hi-res pics
and took these to a graphics company. Not heard of the price yet but they say they can duplicate.
I also found one only of each front side decal and rear decal plus the GTX
decal on e-bay and bought them. The graphics company says they can mirror image these OEM decals fairly easily (in order to get the opposite side decals)
This should cut down my cost quite a bit using this option.
That's about all you can do other than after market decal kits.
jetskidetailing.com is excellent for this.
