all clutch plates have smaller springs encased in the structure.usually they are biased,ie stick out from the center more on 1 side than other.this face usually sits facing towards the gbox(other way they tend to fowl the flywheel bolts.diaphram /spring plate usually sits located by 3 or so steel projection pins coming out of the flywheel face to align the pressure plate.hope this is what u ment.
