I would think this would fall under the same rules or guide lines as say an AC Cobra kit, a Porsche Speedster kit, a 33 Hot Rod kit, 57 Chevy etc...
These all are "New", (you could build one from scratch with all new parts) and they can be licensed and driven etc. So there has to be a provision for the Camaro bodies?
Otherwise they wouldn't be selling them and building them... I'll have to look up their web site or something and see if they address this issue?
