i cant remember if i binned my 2.0l zetec fly, ill go over the garage at the w/e and have a look and take pics to prove.
i know that the std zetec flys take a 220mm friction plate and the 2.0l flys take a 240mm plate
and the cossie one i just pulled out from under my desk

is 240mm
but im not sure on the size of the covers.
but trust me, if doug says it cant be done, it cant!
he spent fooking ages measuring it all
