Here's the hole. I'll have to cut a hole into the side and stuff the stereo wiring into the dash before putting a CB in there. There's ductwork in the back. I may can get another inch of depth by cutting that piece off along the back with a guide hole for the factory double din.
i would mount it either in the cubby hole .which you said was actually a ash tray.
or id mount it to the right of the gearshifter, on the console.theres not a lot of room
above the am/fm radio. especially after you add the coax connector with pl259
on back of radio .plus wires and coax
