This assembly includes an important black plastic frame piece found near the bottom of the rear of the IBT module. This black plastic frame piece has two holes into which the 2nd BTR indexing pins seat, to hold the two modules in the proper relationship to one another.  Sometimes if the big drawer with the 2nd BTR assembly gets slammed closed too hard, this black plastic part gets damaged.  

Note that the BUR Coupling (they call it a drive nose in the parts book) is part of this larger assembly.  It is not spared in any of the OEM parts books we have seen, but we do have them (see the Related Parts listing on your right).
