you will probably need a new flywheel too. i dont think the OEM dual mass flywheel takes too well to resurfacing, and if its the old pre-TSB flywheel, you will have a hard time finding a clutch to fit it.
I think Luk makes OEM replacements. C-F-M.com has lots of clutch kits for sale. have a look there.
