I have the FMS aluminum driveshaft right now, I am looking to buy a Carbon fibre driveshaft but need to know what the difference is between the different 5 speed trannies. I obviously have the T-5, I'm almost 100% sure this works with my 98 cobras t-45, now the carbon fibre one is on a 3560 tranny, I know some of the 98 99 cars came with this tranny and some still came with the t-45 but i'm not sure if they're the same driveshaft? I'm going to call my tranny shop to see if they know the difference if at all, just hoping someone here knew the difference.
