I have a car by my work today which I can tell is a RS and a convert. It hass SS badging on the fenders under the Ralley Sport emblems and a 350 at the front and a SS grill emblem. However, it has a 10 bolt, no SS hod but cowl induction instead, but has a 4 speed with gauges and a tach in dash. What would confirm if it is a SS. The lady works with my wife and swears it is a SS and has owned it for 20 years. I think someone badged it, but either way it is rare.
