[fiesta8u]

Hey guys while im replacing my gearbox i might as well replace my clutch as it had start to slip a little, does anyone know what size the clutch is? and also on the pumaspeed website which fiesta do i choose my fiesta is a 2006 model WQ LX 1.6lt manual, but on their site all they have is zetec, zetec-s etc etc and have clutch sizes ranging from 190mm to 220mm so im just wondering what size is mine, any help will be really appreciated, thanks.
