I'm sorry you think this ZMANALEX. I am listening and have taken on board all advice. Information about clutch supplied is the only thing I haven't got as it was delivered straight to the garage that is doing the work. I/we know how to get round it but again as stipulated previously was originally wanting to change like for like with the original 240mm nissan clutch but this is not an option. Looks like there is no clear reason as to why it came like this because there is no clear answer.
