4" lift...setting rear pinion anlge questions

I will be putting on a 4" lift on my rig soon and wanted to understand how to set the pinion angle and line it up properly with the output shaft of my transfer case. Not finding much with search option. I will be usin Rubicon Express upper rear adjustable control arms and a JB Conversions SYE.
A diagram would be great or any links to any detailed posts on this subject. I've not done a lift before but willing to learn and need all the info going into this as possible. TIA!

With a SYE you will need a new CV driveshaft. When setting the pinion for this style shaft you want to point the pinion directly at the SYE yoke.

A much simpler way to put it--the pinion angle and drive shaft angle need to be inline. You should be able to draw a straight line down the middle of both.
