Thanks go out to Bobby for having three Marti Reports run. Two of them came back as SSP Mustangs, and are part of the GSP group from 1983 -

The third report was for a possible GSP from 1987. It was an educated guess which did not pan out for us. Still, the Marti Report DID turn up something interesting (check out the second option listed).
