I am still in the middle of my KITTAZ build, but I wanted to show people how I added on the LCD and SD card reader. The upgrade instructions leave out some details, which ended up making the process take longer than needed. Here are some important details and pictures.
For one, deep in the description of the purchased items on the Lulzbot store, they suggest you need a few misc hardware (like M5 T nuts, M5 washers, M5x 8mm screws and some M3 and M2.5 hardware too). You need all of the M3 and M2.5 stuff, but you dont need the T nuts, or the M5 washers, as you can just use the ones from the corner bracket that you remove in installing the LCD (the front left upper). The corner bracket and the LCD case are different thicknesses by about 1 washer or 2mm, meaning the M5 x 8mm screws are useful as replacement ones for the M5 x 10mm screws that hold/held the removed corner bracket on. If you dont want to source the 8mm screws, its easy enough to just add a 2nd washer on each of the 4 screws that hold the LCD on, if you happen to have spare M5 washers, or if its easier to source them.
I hope this helps anyone planning on the upgrade to the LCD.
