You are looking for a 28 spline 9 inch, locker, limited slip, or open, your choice.

Expect to pay $50 for one that needs a complete rebuild, and $400+ to $1200 for rebuilds that meet or greatly exceed stock specs.

If you didn't break your case, yours can be rebuilt as well, again, you can add the locker or limited slip.
