Just bought some calipers, any ideas if I can make them fit?

I started the True C5 Rear Disc w/ internal parking brake in the works thread and will have a matching solution to the McGaugys 13" fronts (brackets are getting cut this week... I was also thinking about using the 13" rear C6z06 rotors but they only come cross drilled... and you would have to buy the front to have a matched look.. Im not sure if the rotors (c5 and zo6) are the exact same offset but just larger? if they are you could just use a c5 caliper on the zo6 rotor and still have the internal ebrake...
I havent gotten that far with mis-matching corvette parts... plan to
