Ok so here it goes:
At first i thought that the ABS and non-ABS driveshafts were completely different, when connected to the same transmission. In reality the only the part that is different is the rear section of the driveshaft. The front sections are identical.
But here is the small dilema... i also need to do an auto to manual swap. this requires me to replace the front section of the driveshaft.
So, in conclusion the only thing i need to do to convert my Automatic ABS equipped 240SX to a Manual ABS equipped 240SX, is swap the front section of the driveshaft.
The beauty of this is that i can use the front section from either a 5 speed ABS 240SX or a 5 speed non-ABS 240SX.
This should make my part search much easier.
Say I, if you find all this info to be true!
