Help with Double DIN conversion

[Jamesp]

Very nice interior epapp! What are the controls (or lights?) in the batwing?

Still working on the install, the AC controls only pull out about a quarter of an inch. I am going to have another go at loosening the wiring harness. Leaning toward double DIN in the bottom for simplicity of installation. I've been thinking about pros and cons and have not come up with a compelling reason to choose upper or lower installation. I think that I just have an unfounded preference for the upper position. The question is how much work I'm willing to do to enforce that preference, particularly while working in 104 degree heat.
