This is what my 85 looks like, I have put both a fullsize and a compact CB under my stereo in other rigs I have owned. When I did the fullsize I had to eliminate the plastic switch bar across the top and move the stereo up but with the compact CB I just removed the bottom pocket added an elbow to the coax and tie wrapped it to the stereo. There was also some trimming required to the air box behind the stereo.
