I had a broken clutch cover (the black plastic cover between the screen and the keyboard).
The instructions were very helpful, but I had a few issues (see below). Very happy with the end result with the crack in the clutch cover now removed.
STEP 11 - I had a stripped screw - Phillips head (first time this has happened) when removing the camera cable holder. I used a Drimmel power tool with small spinning disk to cut a single groove in the top of the screw. I then used a regular screw driver to remove the screw. I got lucky because I had enough room to use the spinning cutting disk.
