The Torx driver indicated wasn't included in the MK3S/+ kit and is not included in the MK3.5 upgrade kit, I would suggest listing the required Torx driver size so that an alternative can be used (I can't remember if it was T8 or T10. Also, the steps in this chapter reference the universal wrench, which has also not been included for MK3.5 upgraders. I'd suggest listing required wrench sizes or alternatives. The M3 nuts require a 5.5mm wrench; I'm not sure what size would be requied for holding the expansion joints.
