Well, like virtually every project I undertake, this one took longer than I thought.
If you use the bolt method to install the nutserts, make sure you use grade 10.9. I used a weaker bolt and nut at first, and wound up having to run to the hardware store after the nut cross-threaded on the bolt.
I used 8mm nutserts and bolts.
I also thought I could get away without having to remove the headlight, but the lowest nutsert pretty much requires it. Around the same time, I also went ahead and removed the air cleaner box, just to free up all the space.
In terms of how the bracket looks without the compressor installed, it looks pretty much exactly like the image posted earlier in this thread. I started by drilling the upper left bolt, then the upper right, then the bottom right. Part of what took me so long is that I installed the bracket after every nutsert installation to make sure everything was lining up okay. For the bottom right nutsert, the sheet metal sits a bit more vertical. After I drilled the hole, I used my circular file to bend the metal there to be a bit more horizontal.
Here is where I am at right now. Still have the wiring to do. The KAON mount for the switch will be nice. The second shot is a mockup of the air connection to see how high it sits.
EDIT: I went ahead and grabbed the image from earlier in this thread in case the guy who posted it decides to take if off imgur. That is not my installation (on the tan LR4), but mine looks pretty identical.
