fitting clutches isnt fun but its not impossible, you will need a very good set of ramps (your going ot be inder the car for a couple of hours), gearbox oil, a set of alenkeys and about 1 day on your hands. you will need to take the pas side drive shaft out, then unbolt the gearbox. then you should beable to see the cluch throught the gap between the box and the engine, unbolt it in the space you have and git the new one bolt it all back together, engage and regit the driveshafts and then fill the transmission back up and your done.
Now if you can do it in a day your doing well so that may sound easy and if the enigne is out of the car it is, in the car is a nightmare and not somehting i would want to do when i have a mecanic to hand who does work for me for £80 a day and i know he can do one in around 1/2 of a day
