Big bolt pattern axles drum brake

Oldmanmopar, I have a 67 Barracuda with 8-3/4" rear and Kelsey Hayes discs up front. I'll like to go big bolt pattern as well, are the mustang rotors a bolt in with the existing calliper assemblies? Can you please provide some more information?

I know you were asking someone else but the short answer is no. Mustang rotors have different diameter, different bearing locations in addition to the bolt pattern you want. To use the mustang rotor, leed brakes and ssbc both use the mustang rotor in their conversion kits.
