[AT] Turning Balers and Haybines

[Cecil Bearden]

Al:
That is correct, when building a new drivetrain, the engine/transmission 
angle and the angle of the differential pinion have to be the same to 
prevent an angular velocity vibration. Same thing happens when the 
derive shaft yokes are not in the same plane on adjacent yokes.  Thus 
the need for the master spline on the vehicle driveshaft.
