I killed the inner side (metal part) of an X.0 RD cage (and a hanger!) yesterday. The front (carbon) side is fine. Is there any way to get just that part of the cage without getting the entire ($90) rebuild kit? I tried looking for X.9 rebuild kits so see if maybe I could just get a cheap one and scavenge the cage part I need, but I can't find one.

Anyone know of where I could find just the inner cage piece? Anyone have a spare one they need to get rid of?
