Ray, for the bell cord just use some .010" music wire and run your own. The missing parts are brass. Not sure what Lionel uses but a good super glue should work. The Lionel parts are likely cast with tabs or fingers that fit into the holes. PSC or Stevenson parts won't have these tabs so you may want to get some brass wire that fits the holes in the shell and drill a hole in the piece so you can glue or solder the wire to the piece.
