I had some issues with reassembly which the guide didn't warn me about:

1) a tiny metal bracket holding one of the airport connector cables (visible in step 12, just underneath the leftmost torx screw) got caught underneath the hinge, partially blocking the hole for the leftmost screw - I had to remove the display again.

2) When I completed the reassembly, I realised the screen and the body of the notebook were subtly misaligned (1-2mm), which caused a slight clash on opening the lid and a poor fit for the lower case. I had to go back and loosen the six torx screws to reposition.
