One other comment on the re-assembly. You can keep the three hinge screws loose and run your fingers down the seams on the two sides and front to align the display before tightening.
Do yourself a favor and order the tools along with your display. I made the mistake thinking the bottom case was a standard torx and was surprised. The tools were not available in the local stores. I ended up ordering all the tools by clicking on the link where you goto order the display where it adds all of them to the cart. The tools are high quality and include the convenient finger tip end that allows the screw to be turned while keeping the screw steady and pointed in the correct angle. I am very happy with the tools and the display. I broke my screen when it dropped 2 feet from a chair to a carpeted floor and broke the bottom left corner 2 months after the retina first came out. It was fine except the screen was black till midway between the apple menu icon and the first pull down menu in apps until the display started to flicker lately and turn all white periodically.
