Information needed for '86 AZ SSP mustang

[ChrisL]

I've got an '86 AZ SSP mustang, from what I can tell it served with the Prescott AZ police department at one time, then became a dare car. Would Prescott Police and AZ DPS be the same thing? If not, does anyone have any pictures of a Prescott, AZ police car? It was a white '86 SSP, Blue interior, no console, only options are tilt wheel and A/C. It has a center mounted antenna on the trunk, had a light bar, and single spotlight. It looks like it would have been setup exactly the way an AZ DPS car would have been. I need to figure out what the correct siren is, which antenna I need for the trunk, and what interior equipment I need.

Any help is very much appreciated.

Best,
Chris
