Sorry for such a delay, but the kegerator is finished!
First- Remove inner door shelving and attach replacement plastic. (no Pic)
Next- Bend down the freezer shelf after letting it sit turned off for awhile (also remove thermostat from shelf):
Once the shelf is bent down, take your measurements and double check where you want to add the tower (make sure you account for the base of the tower). Once its measured, drill a pilot hole and then use your whole saw.
Always measure twice and double check your calculations! As you can see, I messed up math the first time and was off by a substantial amount.
Next, line up your draft tower, mark the mounting holes, drill them out and attach your tower.
Finally, remove the top piece of plastic, add draft parts and drip tray(i have purchased a larger one, not picture)
