You cable guide/stopper has a stopper for a piece of outer casing that goes from this bolt-on part to the front mech. The front mech should have a stopper as well. Several older type front mechs do.

Of course, you can try to find/buy a bolt-on cable guide for front and rear mech (the most usual model, used on almost all geared road bikes till late 1970's.
Suntour, Shimano, Campagnolo, etc...

But you can also drill a small hole in the BB-shell (bottom) and cut M5 thread. Then use a part as suggested by Pifko. Then, the cable runs underneath the BB-shell.
It's your own decision if the cable for the rear mech will be routed over the BB-shell or if it will go below the shell also. Of course, this is only possible if there is no braze-on cable stopper on the RH chain stay.
