On step 41 the 1.4 mm T5 Torx set screw remember that this screw does not come out. I was racking my brain for like 30 minutes and realized that this screw is not and can not be removed, rather it's just used to adjust the sensitivity of the clicking on the mouse pad.
I got mine out, but it was unnecessary for the procedure. You're right that it doesn't hold anything down really.

I had a Torx 6 in order to not strip the screw...
I spilt liquid on my MacBook Air and luckily only busted the keyboard, mainly the power and right arrow key buttons.
I purchased the uppercase from iFixit and it is a good quality part. The install took about 45 minutes, but there was a good hour of troubleshooting afterwards. See my comment on connecting the I/O connector cable above.
After doing any sort of hardware install, especially one as extensive as this, run the Apple Hardware Test application by holding down the D button while booting. It looks at a range of issues that you might miss (like a fan that doesn't spin!) that could cause you problems down the track.
Happy repairs.
This was an awesome and clearly understandable guide, helped by color-coded circles for the various screw sizes! I disassembled, replaced the top and keyboard and reassembled in less than an hour, with my son watching over my shoulder. Well done!
