The flywheel should work. You cannot use an early model because of the 28oz imbalance. As for the clutch disc, it shouldn't matter as long as it has the same diameter and spline as the input on the NP. I do you know what size discs the flywheel accepts? I would stuff as big of one as possible, the larger the diameter, the more abuse it should handle. If I remember correctly the clutches can range from 10" to 11.5". The 11.5" may only fit aftermarket flywheels. That is standard size on big blocks. Most car apps were in the 10-10.5" range, but believe trucks(including EB's) were 11".
