The first step was installing the chassis. I wanted to use
@Mountains2Metal in dash bracket, but the space above the glove box did not fit. So onto plan B.
There is a reasonably large amount of space behind the fuse pannel on the drivers side. I was able to use one of the existing studs to secure the radio back in this space. Because the radio speakers are on the chassis, it made sense to me to have it where I could hear the unit. There is also a speaker in the mic, but I didnt want to rely upon that. The radio also has a programming cable port on the side of the chassis, and needed to be able to access that, so I ran a waterproof cat 5 pass through to that and stuck it under the dash where I could get to it.

With the Cable pass through

The stud in the picture is what I bolted the mounting bracket onto. Gives me about 3/8inch of airflow between everything.

This is the view from underneath. I wanted to keep my cables accessible- I am not 100% on the antenna position yet and did not want a big deal to move it. The head cable plug into the front of the radio, so I plugged it in and positioned it straight up in behind the fuse box.
