I just finish converting a 1995 T4R 4X4 V6 from automatic transmission to a manual transmission. After noticing a vibration that only occurs at about 60 mph while cruising (not accelerating or decelerating, I checked my driveshaft and noticed that it is over-extended and theres a bit of back and forth movement when I grab it and shake it (that sounds bad). I had heard from the forums that I could use the same driveshaft for the 5 speed as the auto. Are the two driveshafts the same length? Am I going to have to buy a driveshaft from a 5 speed T4R?
