I haven't been able to find anything. What about just using pictures of actual crown vics?
Maybe take one of your squads and with a digital camera, take a front, rear, side and if possible, roof pictures. Make it black and white so they can circle wherever they need to. Just a thought I had in the meantime.
"Fight and you may die. Run, and you'll live. At least a while. And dying in your beds, many years from now, would you be willing to trade all the days from this day to that...for one chance...just ONE CHANCE to come back here to tell our enemy that they may take our lives, but they will never take OUR FREEDOM!!!"
