Zed, welcome to the site! My wife's cousin is married to a retired New Jersey State Trooper, and I remember him at family gatherings going on and on about how much he loved the 1972 Dodge/Chrysler police cars - they were his all-time favorites.
I'm curious, is the in-service picture in your first post a photograph of your car? That would be very cool if it was.
(even if not, it's still cool!
)
