I really did not understand your question. I am sorry about that. The first thing you have to check, is if your t-case is for a driver side drop, or passenger side drop. Then you have to look at your GM front axle, and see if it will line up with your t-case. Your drive line angles, should not change much, depending on how much lift you are wanting. If you are mounting them on the same springs, you should have approximately the same pinion angles. I apologize for my lack of understanding, of your first question.
