What the hell happened to blow apart the rear end? Those things are usually pretty solid, its usually the axles that go first.

Rear end rebuilds are expensive if you don't do them yourself. I think 900 sounds about right. My boss paid something like 1200 bones to rebuild the rear end in his '95 Firebird. Don't know how good your skillz are, but I rebuilt my rear end myself with the car on jackstands in a 1-car garage back in my college days with a bunch of hand-me-down tools. Do your homework and don't cut any corners, and you can do it yourself.
