Outer Limits 4x4 Board

hey i'm doing a bit of research regards engine swap for a td42 gq patrol, i understand the gearbox is FS5R50A, I'm after specifications/codes for the clutch,flywheel housing. have looked on the net and might not be looking in the right spot, if you can help i would appreciate it.

Im not intending on doing a engine swap its for a tafe report. Thought i would do it on something that could be usefull for the future.
