...sent me the Special Equipment Parts List he has as part of the documentation on the car. It turns out that there were 59 SSP Mustangs ordered under that DSO, where some went to Saleen, some went to the OSP, and some were sold retail. The numbers as I understand them do not total up to 59 units, so I wonder where the other cars ended up?
