Still seems like you'd want to protect the VX first since it shares no external body panels, lights, or glass (possibly excluding the front) with any other vehicle. Sure there were only 1500 RS's, but there were hundreds of thousands (maybe more) Troopers with compatible body parts made during that time. Seems like the only thing that would be unique to the RS would be the doors (often longer than on four door vehicles, but maybe not) and rear quarter panel.
