I skipped the whole issue by using a Cobra C75WXST.. all the controls are on the handset, so the "box" is a very small piece that mounted easily behind the glovebox. I've seen alot of interesting mounts.. N3ELZ has his hung from the headliner, I've seen them mounted to the kickpanel near the parking brake pedal, I saw one mounted in the drivers door map pocket, under the ash tray, mounted to the front of the split bench, built into the floor console (automatic truck).. the possibilities are endless! Your box looks nice, and has alot of room for upgrades, which is cool. I would upholster it in some way, but thats just me.
