I helped my mate do one the other week on a Y reg ka. I know for a fact there are 3 different cluthces as some are cable and some are hydraulic, It was a pig to get the box off and out the way to make room to work, be prepared and patient thats all i can say, they are starightforward enough to do really if you have any mechanical skill. Just make sure you have something to centre the cluth, Either a clutch alignment tool or some people use a Big extencion bar , Ive even seen bits of wood used, Eg Brush handle etc
