A buddy of mine put one on his 86 pickup. After a year or so, he said it wasn't worth the time or money. You are higher up in the air than a Crown Vic, they aren't much use for anything on the right side of the vehicle, unless you do both sides like a patrol car, and they weaken the pillar. After watching his project, I stuck with a hand held one that plugged into the cig lighter. If you are chasing animals, you are going to be one hand driving and one hand operating whatever light you have anyway. The handheld light gives you more options and you don't have to run fixed wiring. If you want it for lighting up a campsite or another vehicle, regular driving or fog lights will accomplish the same thing, you just have to point your vehicle in that direction.
However, if you are hell bent on getting one, just call and ask a small police or fire agency where they sub-contract out there fleet work. Large departments do their stuff in house. Small departments use somebody local for the install. They can probably get you used stuff and provide some advice on install, if not do it for you.
