The motor and worm gear are both purchased separately, you don't use anything from the original motor. The worm is just pressed on, that could be a challenge if you don't have the proper tools. The shim is the sticking point I suspect.

While the gear is technically an interference fit, its less than .001 smaller than the motor shaft assuming is an actual 2mm. A bit of heat and the gear should just slide on.

Good to know about those 370 Mabuchis. Likely ideal for this project not only for overall size but small shaft diameter given how small the gear is.
