If you look at past history of Shelby, he (they) always were in batches of three, whether for race cars or for special projects.
Sounds like yours is one of three, which is what I suspect, and yours was never used for the project.
There was commentary that indicated the cars were sent to Amerisport for "legalization".
Kirk Evans, I'm sure would have the specifics on them since he is Amerisport.
Hopefully he will chime in on what he knows about them?
