This is how I have mounted my scanner - my handheld CB is kept in the frontmost roof compartment. I molded a piece of sheetmetal that tucks and locks under the shifting console and is velcro'd (just love the stuff!). The concept is the same for a CB - you didn't mention the style so obviously this mount wouldn't work for the dash mount type. Midland just came out with a reletively inexpensive CB/SSB combo dash mount unit that me thinks I will pick up. My plans are to mount this in the center console (I have KC Captain's seats) and move my CD's to the back. See (
