Flywheel was uhm.. I think 17mm 12 point socket, and clutch was 10mm 12 point, which I did not own. Not sure how I did this last time. Will have an image in a sec showing the flywheel holder I got gifted by a friend. Possibly Snap On, but exactly the same as the ~$30 OEM tools one on Amazon.. which I bought before they gave me theirs.
