Yeah, Ifixit is SOOOOO great except for explaining reassembly steps that don’t just involve ‘reverse order’ like this %#*@ bottom case. I did a whole display (yay me!) and am now stumped as to the last step of reassembly. If you just put it back on and put the screws back in, there’s an increasing gap from the rear 2 screws to where the display hinge begins (that sits flush before taking it off). There seems to be no ‘popping’ it in place and the pegs on the underside of the cover are in the middle.
