I bought a KE70 with a bigport 4age (silver with black writing on the cam covers). It desperately needs a clutch. What I want to know is where does the clutch come from. It's got a sprinter gearbox so which clutch should I buy. Will an ae82 twincam clutch work??? I have not idea. What do I ask for at auto1 or wherever I decide to buy it from? Anyone got any ideas?????? Thanks Daniel
