I've seen a few articles where the department did their own upgrades.
They were having problems keeping up with cars equipped with aftermarket parts. So they added some performance parts, and safety equipment. They featured it in some Mustang magazines.

I'm sure you are most likely right, aftermarket.
But it seems like a possibility that it could have been used in service like this.

The subframe connectors look old, and were welded on (similar to the wields for the c pillar and rear fender antenna from decommission).

I did a car fax on the car, and it had no DMV record until 1994.

From what I remember about the cars history from the man I bought it from.
The car was owned by a young dumb kid, and he didn’t know how to work on it. So he took it to a local automotive shop, they did repairs to the car. The bill was never pair, and the car was sold to another mechanic as a lean sale. It sat for a while and then I bought it in early 2011.

The subframe connector, rear coil over and 4 barrel eddlebrock carb is the only thing changed on the car when I got it.

I was hoping someone else might of had someone setup like this, but I guess not.
