Thanks for the awesome write-up Minuit! I learned a lot from this thread.
I wanted to share a couple other radios that you might find interesting.
Here's a "Jeep" AM radio, similar to the AM/FM AR-7600 radio built by Mitsubishi. This radio is model AR-7900YJ, making it somewhere around 87-95? ish. I am guessing these were offered as a standard option on the YJ's through '95. (Sorry for the poor quality photo, this radio is not mine!)

Here is another odd version, similar to the AR-7550 you had posted earlier. This radio is model AR-7660X. (Sorry for the poor quality photo, this radio is not mine!)

Lastly, here is the original brochure page from '93-'95 for the rare Anti-theft "pull-out" radio cassette player (model 82201470), as well as the hard to find CD player. The cassette player could have been offered in the accessory brochure from 88-92, but I can't seem to find copies of the brochures to verify. I will take some additional photos of the 82201470 lit up and working. It is a great sounding radio and works surprisingly well!
