I have a spec 3 clutch and im not sure if it came from a t 56 mustang or what it came from, but i have a t56 from a 2000 ws6. The 6 puck clutch slides onto my 26 input spline on my transmission on the ws6, so would that mean that it will work in my car?

 

What is the diameter of the disc?

 

Its not just whether or not the clutch disk will fit, it also matters if the pressure plate will bolt up to the flywheel.

 

NVR is correct. It isn;t just about the disc. Have you tried to bolt the plate to your flywheel? Do you have any pictures of the plate? If so, post them and I will be happy to identify the unit for you. Thanks!
