With the dimensions in the spec sheet PDF, I've accurately laid out the locations of the LCD mounting points on my posterboard blank, and test-fitted it for size in the dash.
The picture shows the four mount points in red, and a blue and a green line.
The Blue line represents the thin plastic stabilizer support bar that's part of the lower center console - this part may need to be cut away for the LCD to fit, but as it's not a critical part, it might be fine.
A replacement lower center console is $30, so it isn't a big loss if it needs to be replaced.
The Green line represents the sturdy upper support bar that is part of the upper dash, and you do not want to have to cut this out, as you would have to replace the entire top dashboard.
Thankfully, this upper support bar will also provide an easy way to secure the upper part of the LCD, by making a piece to fit the support bar exactly.
The result should be a mounting system that sits in place securely without having to screw it to the dash's plastic.
This post in my Fabrication thread shows the rubber blank I made for the right-side mounting block, which will be extended down to support the lower right mounting point:
