[MOstang]

Have you mailed a polite letter to the Chief of Police. Maybe sent him/her a letter explaining a little about this niche of the Mustang hobby and your desire to validate if it served with them in order to learn about the Mustang's history.

I had success in this manner with the Missouri State Highway Patrol and they are very helpful in this respect. On the other hand the same approach did not yield results with the North Carolina State Highway Patrol. Fortunately in that case I was able to make friends with someone on the inside of the NCSHP via other contacts.

Good luck!
