You can also use M21 gear, probably Persona as well. Not Jumbuck. Handbrake cables need to be from a M21 or GTi if you have a coupe, or Persona/Wira/GSR etc if you have a sedan. You can use sedan cables on a coupe but not coupe cables on a sedan.
The assembly itself will be bolt-on, no modification necessary. Just a bit finnicky and a *Richard*-around. If you haven't done anything like this before, set aside most of the day.
