You have to be patient...this isn't Facebook.
If you've kept everything in order, it won't be difficult to measure your old "driven" plate, to determine the thickness required for the replacement.
There will be 8 driven plates @2.3mm...possibly a 9th, if not it will be @2.0mm or @2.6mm.
It's kind of confusing and awkwardly worded.
As the fiber drive plates wear down you can add thicker driven plates. You can add or subtract the "clutch stack height" with these plates, Less height, less pressure on the springs, less pressure at the lever, too low and clutch will slip.
Clutch slipping ? Add thicker plates.
The drive plates (fibers) are 2.8 ± .08 mm thick and the driven plates (steels) are 2.3 mm thick. So the nominal stack height is 10 * 2.8 + 9 * 2.3 = 48.7 mm. The extra plates allow you to measure the stack height and adjust it if the tolerances combine to move it away from that value. As Beairsto says, the manual could do better.
