it is a real rally sport for sure, i had a rs/ss a few years ago that i did a restoration on. as far as the ss goes, it appears that someone may have tried to make it into a ss. the ss emblems are not centered in the fender stripe. the ss should have a tach in the dash, and there should be a 12 bolt rear under the car. if it is a real ss/rs then the ss ebmlems,horn cap,gas cap will take presadence over rs emblems.
