I agree with sinwillet’s comments above; I repacked the battery and trackpad and did not remove the speakers entirely or the I/O board data cable

Note that the replacement trackpad may not have the ribbon cable or it may be the wrong length. Ok because you can reuse the ribbon cable on the original trackpad, as Philippe suggested above.

Yes, the comments on incorrectly described screws are similar to those on step 15.

Silver screw is 6.8mm. The 6.3mm screw is the other blank one, closest to the trackpad/SSD.
