I`ve spent quite a bit of time trying to find out what clutch to use to mate a Zetec 1.8 & type 9 gearbox, various forums/threads mention this & that but if you need any specific data I have found quite an interesting catalogue on the Quinton Hazell site,
http://www2.qha.com/catalogues/QH08.pdf, this gives data for which clutch fits which car, but also lists diameters, number of splines, boss diameter etc if it`s of any use to anyone
