If I am understanding this correctly the Pantera studs are too large in diameter for the Mustang rotors.
I personally have no problem using the Mustang studs BUT I would look to honing the Mustang rotor holes out to the Pantera dimensions. That's something that I can do and therefore it is fun and cheap AND I'll be able to get rotors for ever.
Now I just need to find a metric hone of the correct dimension. I'll bet it's 14mm.
