There are a couple different clutch fork styles, open ended and closed ended. In anycase they are interchangable and dont matter flat v's dished flywheel.
Pretty confident in saying the pivots are one in the same.
The difference in assembled height of dished vs flat flywheel and corresponding clutch and pressure plate is not that significant. My understanding is that it is negated by the clutch realease bearing. The flat flywheel version is taller than the dished flywheel version.
