Ok well thats a strange clutch to have in a Datto
Since its for a Ford Laser
You sure about that number ?

Perth Brake Parts is an agent for Extreme clutches. They don't carry any in stock but they can get one in for you
However..... making sure you have the right thing to start with will be the issue
They sell boxes with clutches in them... they don't mix and match parts.
Their clutch experience is very limited as they only started selling clutches in November.

Maybe take the clutch to Graham at The Clutch Factory (Precision Clucth) in Dowd Street Welshpool and get it identified first
They can build performance clutches there too
They did the one for my racecar with A series engine and Toyota box and clutch.
