I don't know who's pics you were talking about, Zaphod, but I reworked our website so the links changed. Unfortunately I can't go back and edit my original picture post, so I'll just rewrite it here (with a little addition at the end).
Now you see it:
Now you don't:
And the antenna is basically a mirror image of the stock one so it looks 'ballanced.' and hopefully inconspicuous...
I didn't have the Kenwood TM-G707 powered up because the battery is as dead as the motor. I used a dremel to remove most of the plastic material on both sides of the pocket, and when I later removed the dash to replace the leaky heater core I added a small brace on each side to replace the material I had removed (that's what the machine screws are that you can see on the inside of the hole).
You can control all the functions you need from the keypad on the mic, so all you do is pop the pannel off and then put it back when you're done for the day, no reaching all the way to the base of the windshield to change channels or whatever else you need to do, other than squelch and volume which are easiest done from the head unit.
New info: I mounted the smallest speakers I could find above (I think) the 6X9s that came in our Amigo, on the flat pannels just in front of the rear side windows. As I recall, they were 4ohm speakers, so I wired them in series to get the 8ohms that the radio is rated at for an external speaker, and it sounds really clear even while on the freeway. I used a regular Ethernet(?) cable as an extension for the microphone, and also ran the programming wire out with the same wiring bundle, so it's now "part" of the vehicle, so to speak.
