ok here is one for you guys doing sr swaps... 300ZX's have a balanced 2 piece shaft just like a 240. When doing a swap mark the damn shaft since you are disconnecting it in the middle. Just disconnect your driveshaft in the center and turn it 180 deg around. They can only go 1 of 2 ways... you probably have it exactly opposite. this actually doesn't make a difference on 99% of the cars but I've had 1 300ZX and 1 240SX I've worked on where this was exactly what happened.
