ok i really need help..... can anyone tell what the difference is in supercharger setups between a 97 mustang gt and a 03 mustang gt...i was going to buy a used powerdyne kit for my 03 gt but when i called powerdyne to make sure it would fit the guy said that it wouldnt but never really told me why. i know that the 99-04 mustangs need a reverse rotation supercharger...yet im fairly sure that the 97s take the same thing...so what is the difference???? someone tell me PLEASE.
