Joe Well, you are dead wrong in your assumption, have you done this swap, or are you assuming this as a fact? You are right about the front shaft angles not changing, but you have to consider that the front shaft (which is the shorter of the two already) will be even shorter, thus the angle of the joint at the trans end will be pushing the limit for acceptable angle. This becomes even more important because the factory design of the engine/transmission mounting is set at a 6 degree downward slope, not a the 3 degree industry standard. Even if the front shaft u-joint doesn’t move it still has to be in the acceptable range of angle to avoid vibrations. Running the rear u-joint and pinion yoke angle the same, with the CV joint in the middle taking up the slight differences that occur with suspension movement is the best way. After buying two drivelines assemblies and trying three sets of different driveline combinations when doing my T5 swap, that’s what I recommend from experience.
