Those wrecking yard prices are too high for these wheels. You can buy brand new ones from Ford (wholesale) for about $75 a piece. Why take a used wheel for $60 (probably plus tax) when you can get a brand new one. Wrecking yards need to charge no more than $25 a pop for used wheels. Make them an offer if you want but $60 is craziness.
You can also try Sport Tracs and Explorers. Their steel spare is the same as a Crown Vic. Also no difference between civilian and PI wheel.
