I'm trying to remove the radio of my 1990 ls400. I got the wood plate off around the shifter and the air outputs. I read online that you need to reach under the ash tray and pull and the clips will release. I did this, but it wouldn't release and i'd like to know if anyone has a better description of what to do or how exeactly to get off the wood plate around the ash tray so I can get to the two lower screws. Any advice would help thanks.
