The angle of the rear shaft joints should not exceed 4 degrees and the front shaft will have to be set to not exceed that either if possible. The most desirable situation is to have the front joint on the transmission and the rear joint on the slip yoke or differential the same so they cancel each other out. Avoid extreme angle as was mentioned above. Those are not everyday driving set-ups and parts may only last for a single event. Incidentally it is just as important that no joint operate at a zero angle. Remember too that a side angle is sometimes possible as often seen with an center offset differential carrier.
