yey or ney?!

got a clutch from a cossie that was fitted in a car tranverse with an MTX75 box, hoping to run it on the zetec but dont know what diameter the cossie clutchs are?

its running a zetec flywheel with S2 ERST clutch and box. the input shaft on the box will physically fit the clutch, but not sure if the diamters are similar. banking on having to drill the clutch or flywheel but can anyone shed anymore light on the subject?
