A 1990 NCSHP Mustang recently popped up, which I just added to the VIN Project -

And here is another 1990 NCSHP Mustang
with the same DSO number, but with a VIN that is over 1,000 numbers earlier -

So it's the same DSO number, but from different batches of VINs. I've seen this before with some 1984 SSPs, but none this late in production that I can recall. It's an oddity in terms of how Ford sequenced their orders. With there being civilian cars in between these two VINs, it sadly demonstrates that finding a VIN in between two SSPs with the same DSO number does not guarantee that the car is a SSP as well. That is one of the reasons we do not make any assumptions when we add a car to the Project.
