Ok, the clutch came in today. Unfortunatly I wasn't able to get any work done because my standard clutch started slipping. Ill have to fix that first, then move on to installing this one. And just to be safe then sorry, id rather spend some time making a notch in the clutch and securing it with a key. Because if it slips and shreds the shaft, and I would have to replace that, that would be too much.
