Question
1. How good are these Diffs
2. What do i need to swap (current diff is Drum brakes)
3. Do I need anything else to swap from a 10 bolt to a 9 bolt.

They are much stronger than the 10 bolts, but parts are more expensive and harder to find, but I am working on changing that right now

You will have to swap in the proportioning valve, figure out the e brake cables and probably some brake line fitting stuff.
