OK, I admit it. Math is definitely not my strong suit. So, I reach out into the minds of those superior to me for advice.
I have all the materials to shorten my rear upper control arms after installing 4" of lift. Using a protractor to measure the output flange, and comparing against the rear diff flange, I show that I need to shorten the upper arms to gain ~4.5* on the rear flange. With the upper control arms being 15.5" long (center pin to center pin), how much do I need to take off that length to get my 4.5* angle back?
