Note for Step 10 during reassembly: Be careful when replacing the screw for the display cable bracket closest to the magnetic power cord receptacle. The interior magnet might attract the screw causing the screw to get pulled under the DC power circuit board which might then require that you disassemble things again to retrieve the screw.
Note to Step 41: the 3.5 mm Phillips screw and the 3 mm Phillips screw directly opposite were swapped in my MacBook. I believe the screws as indicated in the iFixIt guide are currently incorrect as it seems that the location in my MacBook would be correct as all 3 mm screws engage directly into the top case while the one 3.5 mm screw engages into the black bracket.
