It all comes down to what each agency ordered individually, and it even varies from car to car. My car for example didn't come with a roll bar, but the car built next in line for the same agency in the same year did. A lot of them get spotlights, mine didn't. If you didn't know what to look for, you'd never know mine was a cop car. It does have reinforced floor pans but that's basically just an extra strip of steel crossing under where the seats bolt in. Also in my car they didn't start using silicone hoses until '87 so i didn't get any of that, and if it had an oil cooler it was long gone before i got the car. It does have an 8.8 in it though, which to my understanding didn't come standard until '86..but again it could have been swapped in by a previous owner before i got it. I did get the 140 speedo, but my dome light does work (they just take the fuse or bulb out). I didn't get a trunk release button, it came with 3 keys (door, trunk, ignition), and it did have a full size spare. As mentioned already, everything else like the engine/trans/etc was exactly the same as any other 5.0.
