The Cuda was at Carlisle this summer and that is where the current owner first saw it.
The fender tag codes would lead one to believe that there is a strong possibility that this is the car tested by Super Stock.

As memory serves it is a December 1970 Scheduled Production date. The 'R' SO prefix is generally accepted as an executive ordered car.
The tag also includes Y28 which denotes a Company Car/Public Relations.

But who really cares?
A solid body, Sassy Grass, shaker hood 4-10 Dana 71 440-6 Cuda with original fender tag and two broadcast sheets.

To think this car ran ebay twice and sat all weekend at Carlisle with no sale was incredible.

Nice score.
