driveshaft angles
The bottom shows the correct pinion angle for conventional u joints like what we have. The pinion angle is "DOWN" relative to the drive shaft, which is correct for our cars. The specific angle will vary, dependent on WHAT you are doing. The hotter the car and harder the launch, the more downward pinion angle relative to the drive shaft you will need. As I've been preaching all along. All of this is covered in DEPTH in the Mopar suspension and chassis manual. @Oldmanmopar posted the exact text with pictures very recently.
It could be anywhere. See if this helps. The top picture shows correct pinion angle when running a front constant velocity joint. It shows the pinion angle "UP" relative to the drive shaft, which is correct.
