Excellent to hear you are going to do this! do you have a 1 piece driveshaft or a 2 piece? How is your truck lowered? Is it a 5" spring with 1.5" block? is it a 6" spring with some shims under the axle? is it on air? what panhard bar do you have (I'm curios, its has little to do with what we are talking about)?
The more info you get us the better we can help, but a simple rule of thumb on a 1 piece drive shaft is that you want the pinion angle to match the trans output shaft and on a 2 piece shaft you want the angle to be same as the first drive shaft. since every truck is a little different it would be wise to flip the mount get it on the ground, measure your angles, and order accordingly so you have the correct shim and not a guess.
