Wood trim questions

Well I found an Immaculate piece of wood trim to replace my aging cracked wood trim where the power antenna, moonroof buttons are etc. It works out good because I have the manually adjusted AC control which does nothing, and the wood piece is from a 300D. So I am planning to take out the little adjuster for the AC that doesn't work, and put the 300D wood trim right over where it formerly was. My question is, what do I have to do to remove the current wood trim? I don't care if ir gets hacked up, but what is easiest way to remove? I have to remove all of the buttons first I assume...
