I tore up the clutch pack side of my rear diff so I am looking for a new rear end I can use it to rebuild mine. If you have one that is noisy or cracked let me know how much you would like for it.

 

still looking. I need the atf side of it since I blew the clutches in mine so most bad units will work for what I need.

 

I have a blown X diff but I'm not sure what's wrong with it. Here's a picture. Came out of my 2013

 

I have 2 blown ones at the shop. One has a cracked case, the other has something broken internally. Both failed from a customer launching the car. I don't have time to take them apart but you may be able to use some parts out of them.
