Where did you get your front disc conversion?
I went with the kit from Scarebird
www.scarebird.com they use Chevy Celebrity calipers and rotors, and caddy hoses. You just have to redrill the rotors for the small bolt pattern. My mechanic is doing the install now...well, for the past 7 weeks or so. I'll let you know what I think of them if I ever see my car again.
