I am replacing the shattered ring & pinion in my HP Dana 30. Right now it has 27 spline shafts and an OX Locker. Also, possible changing gear ratio at the same time so I will be doing the rear Dana 44 as well. It currently has a Detroit with original shafts as well. I cant remember if I need different install kits because of the lockers. My question is, what will I need for master install kits? Any specific recommendations?
