If you want to try it yourself then here are the steps from when I replace clutches, this is only a small guide and I can't take any responsibility if you break anything of hurt your self.
1. drain oil & disconnect battery & jack up the back of the car about 60cm
2. remove wheels, upper knuckle/ hub bolts and remove drive shafts
3. remove gearbox wiring, started motor, shifter cables and clutch slave
4. remove front& rear engine mounts also the gearbox inspection plate
5. support the motor with a jack and block off wood
6. remove passenger side gearbox mount and lower the engine slowly until it wont go down anymore
7. get another jack and support gearbox and remove the bell housing bolts
8. slowly pry the box back away from the motor and lower it down
9. remove clutch, flywheel & throw out bearing
10. install machined flywheel & clutch with loctite and tighten to spec
Reverse these steps for installation.
First time it took me about 4 hours to remove the box but I now I can do it in about 2,
If you want to do it yourself remember safety precautions, I have had two friends die because the car came down on top of them from using **** stands and only a jack so I can't stress this enough.
