Need help to german Sunfire: clutch partnumbers

Hi there, I own a recently from USA imported Sunfire 2004, 2.2L. The clutch doesn't seem well.
Please help me by telling me the part numbers (SACHS numbers preferred) for
CLUTCH DISC, PRESSURE PLATE AND SLEEVE CYLINDER (ball bearing)

Thanks a lot ! Regards from Germany

The chevy dealership over there would have that. Even if its an american #. they only can order it. I needed some info for my alero, they helped me out, with the chevy alero over there.
