The “equal bit opposite” gets tossed around a lot and I believe confuses many unnecessarily. Parallel should be used instead. Also confusing is when someone says pinion up, when what they are describing is pinion down, like the guy in the video. In the attached pic below both the trans output shaft and the pinion shaft are sloping down toward the rear of the car, (rear of car, not the rearend). The entire pinion gear is a short shaft, (yoke, shaft,gear), and is sloping down to the rear, looking left to right, just like the trans shaft, parallel. Some would describe that as pinion up, but when calculating driveline angles, or using that spicer calculator, that would be wrong.
