You would be better served to take your measurements on the flats of the yoke vs the case. The pinion yoke ears should be horizontal when measuring. Use that number (angle) and match it up against the drive line angle. Split the difference and you will have the number you are looking for. Not a bad idea to subtract a degree or two from the final number to allow for the torque created on acceleration.
