I know it was mentioned several pages back, but I can't just let it go unfixed... Regarding clutch sizes...
96-00 GT is 10.5".
01-09 GT is 11"
96-98 Cobra is 10.5"
99-04 Cobra is 11"
So....99-04 Cobras, and 01-09 GT's all share the same 11" clutch. It was common practice in the early 2000's to replace the 11" clutch with a 10.5 because of more availability and better clutches at the time. Since then, better 11's have come out (03-04 Cobra clutches) and far fewer people are putting the smaller clutches in place of the biggers ones. If the 01 Cobra in this thread had a 10.5" clutch, then at some point in its' life it was swapped out from its original 11".
