6 speed has 19 mm of spline length available. It does not use 6 mm, so only 13mm are actually carrying the load. Thank you GSAddic for the info. If you look at the worn shaft, (and you dont have to look far),
(EDIT: ONe just popped up above this post.)
there is about 4mm that is only partially worn. And you are gaining the second point on contact on the front of the shaft to stabilize the clutch plate further. Both of these areas are "virgin" more or less. So I think that this middle portion would be safely bypassed. Speculation at this point so an official tester would be nice.
