Firends need the disc and a throw out bearing(he had the whole set up and the dude put in the vette throw out bearing...

so the pressure plate is good, but I need the disc any ideas...thanks

Isn't the SPEC 3 bearing attached to the Pressure plate and not a seperate unit? While you may find a disc that would work with the Spec 3 components, I'm not so sure about the throwout bearing. I'd give SPEC a call.
