You need to bleed both circuits together, with the engine running to scavenge the servos.

Agreed. One circuit for the front, one for the back.
On left hookers, both circuits are actuated by a single combined master cylinder and servo unit (and the pedals are hinged under the dash). On right hookers, there was no room above the carbs for the single master cyl/servo, so two master cylinders were put UNDER the floor, meaning that two boosters were needed (one for each circuit) and the pedals had to come up through the floor. Cue a wet road, cue water splashing into the car and around the master cylinders and .... you've guessed the rest. You wont see many (original) RHD Giulia coupes that are not rusted to buggery around the pedals.
