To my understanding, the DCT clutches should last a long time and never really need replacing in a normal vehicle lifetime - these transmissions are pretty stout. And while I have read that the clutches are replaceable, likely you're better off just finding a used transmission as tooloud posted above; it will be cheaper and easier.
