Well, to get all the numbers to work out, you also need to rotate the knuckles.
First off, ideally your pinion should be pointed at the dual cardan at the tcase. The problem with that is the fact that unless you rotate the knuckles, rotating the pinion up decreases your caster. So in an ideal world you would break your knuckles loose, rotate the pinion up and then set the castor by rotating the knuckles. Once you do that, then you would put your axle under the vehicle and set the front to back location, then mount the coil bucket so the coil points at the frame side location of the coil spring.
If you don't want to do all that work, you typically need to split the difference. Put the axle under the vehicle and rotate the axle housing to have the pinion pointing up as much as possible without killing all your caster. I don't have those numbers since my setup is totally different due to a wristed radius arm setup. I am going to rotate mine back down to increase the caster a bit because my rig wanders and does not want to go in a straight line (not enough caster).
