Sounds like you've answered your own question ... wallet out time
new clutch pack, all being well nowt elses is shagged when u pull it apart.
If you decide to replace clutch, do the drilling mod to inner splined hub while you're in there, it'll run way smoother & plates will last way longer, gear changes will be much improved.
Bin old clutch cable too, it'll be well worn & grabby, Genuine is pricey, but a million times better than pattern stuff.
