just to let you know, there is no cheap way out of this. If you car is that torn down you are going to want to replace the clutch while its accessible (espicially if you've been taking it to the track), unless it has alreaady been replaced. Flywheel resurfaced. New trans. New LSD so you dont have this crap happen again. Parts for the new LSD. ..... no matter how you do this its not cheap.
I just spent 2G's doing it all myself.
I'd go with terry unless you think you are a really competent mechanic and have the necessary tools and space.
sorry to break the bad news to ya
