For a T-5 swap did you guys use the stock II driveshaft or did you have to add 2inches to it? Infact my car was an auto before is that drive shaft the same as the 4spd or are they differant? I went to get my driveshaft balanced yesterday and the guy said it looks alittle short he seen the rub marks from the seal and it should be in more. He said that would cause vibration at higher speeds. It does vibrate at 60 and up not to crazy but noticable. I dont even know if I have the right driveshaft in the car.
