Differential

Hey guys I am new here and after a little searching didn't find any answers so here I am posting. I just came into possession of a 01 eclipse gt that has had a lot of mods done, haven't really dove into the car yet. The guy who owned the car before me shredded the transmission doing neutral drops cause the car is an automatic. Idiot. Anyway he got a new tranny but his differential is shot and needs to be replaced. Anyone happen to have an old stock one laying around? I am having a real hard time finding this part. Thanks in advance for the help guys!
