Anyone Seen Wheels Like This Before?

Aftermarket wheels rarely fit the axle register. Magnum 500's for example don't even have a register. The center hole was not hogged out and the wheel is almost 1" thick at that point so there is no chance of them breaking or of the lug washer hitting the register. The register in fact is appears oversized like it would fit over any axle, Ford, GM, Chrysler. It almost appears that they pre machined the wheels and then as needed they added whatever bolt pattern they needed at a later date.
