MMU3 for MK3S+ upgrade parts required for use with MK4/MK4S

MMU2S upgraded to MMU3 for MK3S+.  I am no now looking to upgrade it to be compatible ith MK4/MK4S.

From what I can tell these are the only parts needed? Can anyone confirm?

You still need parts to modify the filament sensor on the Nextruder. Look in the assembly instructions for MMU3 in the section for mounting the MK4/MK4S sensor to see what parts are needed. You can print them yourself, they are listed in the MMU3 printable parts. Some screws still need to be changed and a new round magnet 3 x1mm is needed.
