With the flywheel holder, you also need a wrench to tighten down the 10 mm clutch nut. For this, you could get the Hudy one which also acts as a wrench glowplug and also the other side acts as a 10 mm allen to tighten the aluminum pivot ball retainers in the knuckles. One of the more useful tools in the toolbox for me.
The other option is the 3racing tool. Identical to the Hudy one but at a reduced price. Its one of the few non-Hudy tools I use.
