Nice looking wheels. There's probably a 6-lug version somewhere.
As a general note, fwd vehicles and rear wheel drive vehicles which use front HUBS rather than greaseable wheel bearings will have different offsets than wheels on vehicles which have front wheel bearings (as a normal rwd vehicle). I don't recall the model year, but later Crown Vics use hubs and you can see the difference in the wheels, for example. Plus the wheel covers on the steel wheels they use. The aluminum wheel's center hole is usually much smaller, with a "center cap" of about an inch or so in diameter. This is why some aftermarket wheels are specified as "Front Wheel Drive".
