Ok so I'm planning everything out for my build and trying to learn about all this stuff along the way (I'm not a mechanic at all). I will be regearing the trailblazer to 4.10s from 3.42s, I have had help from some others and they said it is 8.6" 10 bolt 30 spline count. However I have only found 1 locker that is 8.6" and the rest are 8.5" I have been told that you can run 8.5" lockers with some modification. Please let me know your opinion! Thank you
