you can use a syringe full of fluid to bleed the final part , after the normal process of bleeding.
they need to be done properly and are not self bleeding , otherwise they can get a small bit of air that will affect the pedal , more so when first used in the morning , the pedal will travel for a few pumps.
as for the clutch change , its not too bad of a job too remove the gearbox , as when you take out the subframe there is plenty of room.
