I agree that there isn't much difference, but there is absolutely no counterfeiting allowed, and it's up to the competitor to prove to the satisfaction of the inspectors that all parts are legit. I know another guy who has a set of the covers for an '83 and down Rampage, and has submitted photos of the covers, photos of the original boxes, a pic of the boxes in front of his vehicle, etc. to verify the authenticity.
I realize that these are rare parts, but I'm still holding out hope that I may be able to get my hands on a set.
