It would be best to at least have the engine/tranny mocked in. Part of the angle relies on the angle that the output of the trans is at. The idea is hat you want the operating angls of the 2 U-joints to be the same. This is to prevent vibration and to extend the life of the U-jounts. there's only so much angle that they can operate at, usually 11 degrees max, so the setting of both the pinion and trans agles is crucial and they are dependant on each other.
