First, you get some Allen wrenches and take off the knobs. Under them, are nuts. But before removing them, get down on your neck (Hogshair burn coming up...) and reach up and pull the antenna lead out from one side. Then, take the power leads loose. Then, there is a brace that has a nut on one side or the other that you remove. Now, (I believe) you can loosen the nuts under the knobs and balancing the radio from underneath, take the whole thing out. It's been years since I've done this, and will welcome any corrections. But it's not really all that hard to do once you figure out what has to be taken loose from the wiring and the antenna lead. Good luck.
