How do I get this car added to VIN registery

[MOstang]

I like it! Do we know it's a PA SSP because of documentation that ties it out to such, or are we assuming based on the DSO #? Just curious...I certainly hope that it is as that would be great and rare. Noticed the buck tag just has Police, which I've always found interesting. For instance, the Missouri State Highway Patrol SSPs in 1993 had Police instead of something indicating Missouri, while some earlier years did indicate the state.
