If the gearbox has an integral slave cylinder, the bleeder will be on the gearbox casing.
This is where it sits on my Roadster:
Looking at the photo (sorry to duplicate the post but it makes it easier to refer to..), I assume that the pipe running vertically and then dipping down to the right hand corner is going to the clutch pedal cylinder and the two pipes running from below the bleed nipple/bracket are continuing/returning to/from the slave cylinder and therefore you have a complete circuit terminating with the 'nipple'. Therefore easy to bleed.
The issue is that the Zetec set up has a single pipe from the pedal cylinder through a mount on the bell housing and then into the bell housing (never to be seen again!)
I tried to get photos but it is in a very difficult position.
