Here's the writeup...
CB Instructions:
Antenna... I just picked up a magnetic mount one from RS and stow it in the back until I need it, and stick it up top and run the wire through the window or close it in the door, carefully.
first, take off the trim around the climate controls, you'll need to pull out the ashtray and take out the two screws behind it and the whole thing will pull out. Don't forget to pull the little lever doo-hickies for the fan, temp, and stuff.
Second, take out the four screws holding the pocket, it too, will come right out.
Now, take the empty pocket to your friendly neighborhood Radio Shack or electronics store and find a small CB that will fit. The one I have fits perfectly, with about 1/4" space on all sides. I used a dremel tool to cut out the back of it to run wires, and give it a little more depth.
Wiring: easy stuff. I tapped into the power from the cig. lighter and hooked up the ground. Here's the slick part...since CB's that small don't usually have speakers in the unit, you need to get a remote speaker. In my 86 I have the space for a speaker in the dash-pad on top (all those holes). I can't remember if there was a speaker there or I bought one to fit, it's a standard size. That way you don't have a big ugly speaker to install and the sound is right there where you can hear it. I think I had to get to it by taking out the glove box insert.
then, just put everything together and you should good to go. (oh, test it before putting everything together, I've definitely wired things, reassembled only to find I didn't hook up the ground properly or some other stupid thing).
I have crappy picture of the interior where you can figure out what it looks like if you want, I can email it to you.
I have pics of the install, and finished product...but can't re-size here at work. PM me, I'll email...
