Oh yeah, that's a TW DS...
i think what this means is because of the relationship between caster and pinion angle, and also because its worked for others with any combination of upper and lower control arms, that you angles need to simply be within a certain range and there really may not be a "perfect" angle for either. just within a range of difference in degrees.

If your caster angle is too little or too much your Jeep will track terribly and for some reason my steering feels very sloppy. Once caster is adjusted properly the Jeep SHOULD track and handle as well as it did stock (unless you have issues somewhere else)

Pinion angle is set to get rid of driveline vibes caused from too severe of driveshaft angles.

With the belly-up TC skid, 4" lift, HPd30 and 35" tires my pinion angle is within 1 degree of being straight with the DS. I then checked my caster angle and it was at 4.5 degree's which is proper for my setup...HTH
