More disc brake questions

Get ahold of Cass at Doctordiff.com. When I was talking with him about my options for my Barracuda, he said he could get me rotors with my small bolt pattern, then when I switch everything to big bolt pattern, I would just have to switch out the rotors.

It's possible that he has a big bolt pattern rotor you can just use to replace the small bolt pattern rotor you have now. He would be able to tell you if you need to change anything else.
