I tried not carrying anything valuable in the Jeep, but you'd be amazed what worthless stuff people will steal. Click here to see how I fixed the window. Anyway, this left me in the market for a new, more secure, waterproof console and a new CB before topless weather arrived. Tuffy makes a fully line of security storage boxes for various vehicles, including Jeeps. Their Deluxe Stereo Security Console has a locking compartment for a DIN-sized radio, into which many people install a CB instead.
Depth gets interesting, since the mounting area sits at an angle.
A side view follows. The mounting plate is perpendicular to the walls of the box. The mounting plate is only attached at the back side, so it wouldn't take long to remove it with a grinder if you really needed the extra space. The hole in the mounting plate is pretty much centered, but maybe a little closer to the front edge than the back. The mic can be unplugged and kept in the Tuffy's storage compartment when not in use.
