How many miles on it? If its 200k or more, it will need a couple clutch's for sure. You don't really need all of them. You can just order what you need when you get in there. The first clutch you pull will probably be all you will need to replace any discs in. The rest will probably be in spec. Don't be too afraid of it, they are pretty simple.
