1970 DodgeDart SWinger Brake Rotors

I have the original 4 piston caliper on my car with the small bolt circle wheels.The problem I'm having is the new rotors i have ordered have,the bolt holes for the wheel studs are to big, and the hubs hit inside the rotors and can not be pressed in place. The original rotors do not have the machining that the new ones do.All I know is that the new rotors won"t fit
