sr clutch assembly on rb flywheel

[mat180]

i was told an sr clutch assembly can be used with the rb flywheel and be compatible

if the sr and rb input spline #'s are the same, and since the pressure plate and flywheel bolt patterns look the same?

im only asking because i have an sr 14 os giken twin plate that i cant seem to sell and was told it should work by a mechanic i know

anyone have any idea?
