With the early b-body rear the rear wheels %100 bolted on. The fronts I had to put the rotor (75 duster discs)in a brake lathe and machine the snout down at an angle to fit inside the wheel because of the wheel not being deep enough, I also still had to run a 7/32 spacer but the wheel is close enough to the hub to be hub centered. Hub centered is important on this swap because the bolt pattern is not %100 the same. It is something like .3 MM different

You can't really tell in the pic but the chargers center cap won't fit the front because the spindle sticks through it but the grease cap can be chromed and installed after the wheel is installed.
