Disco 2 TD5 clutch help

Can anyone help
Bought a valeo clutch but does not say which face of clutch plate goes against the flywheel, so is it sticky out bit, or flat bit against the flywheel.Already took out old clutch but forgot to check what was what
Thanks

Would say the 'flat' bit goes against the flywheel.
If you just hold the disc against the flywheel you will usually find that it will only fit one way - with the 'sticky out ' facing towards the flywheel you will usually find that the friction part won't make contact with the flywheel .
