im about to do the swap from my 98GT to my new 03GT i have a set of steeda underdrive pulleys installed on my 98 currently, im pretty sure they wont swap right over but cant i just use the crankshaft pulley that's a 1pc which is steeda and use a different brand water pump and alternator pulley?? or does the water pump and the alternator pulley have to be the same as the crankshaft which i wanna use the steeda
