I mounted my Midland 77-115 40 CB today.
One thing is for sure no place in dash that looks good. I mounted it in front of the fixed center seat. I built a small wood box and mounted the box to the floor. The CB slips straight down so face is pointing up. I then carpeted box--looks factory. Ran power wire to radio fuse since that fuse is filtered. I used a Midland 18-258 40 (through the glass) antenna on the rear window on drivers side and reception is very good.
