It is a near zero transition at the universal joint at the front of the torque tube by overall Ford engineering design. Not a single component.. Changing any of the factors Tom mentioned, as well as changing the motor mounts, will change the universal joint angle. Adding a quick-change differential will also affect the angle.

Is there something you are trying to do or (gasp!) modify?
