Right - but I plan on doing a CV style so I won't be matching angles I will be pointing my pinion up at the T-case so there essentially is no angular disparity between the pinion yoke angle and the driveshaft itself.

My question was how do I know I am within the "tolerance zone" of a CV shaft? How do I know I have rotated it enough or too far?

I guess I have been assuming there is no shaft between the T-case and pinion to know when you hit the right angle...Is this what I am missing? So use the stock shaft, set the angle, get new measurements for a new shaft?

CV shaft is perrty forgiving but I would guess if you get out of the tolerance zone you will experance massive vibrations and pinnnion angle too high will mess with diff oil levels and splashablity or slingablity of the gear oil = HOT rearend

For mesurement without a shaft installed just point the pinnion at the xfer case and measure (cap center to cap center), when they make the shaft it will have in/out movemnt that will alow your mesurement some flexabilty, so it doesn't have to be a super perfect mesurement.
