Audio Systems: 1996 Delco AM-FM stereo cassette display lights, mini lamps, chevy silverado

Question
I have the above radio in my 1996 Chevy Silverado Z71 truck.  The cassette is built into the radio and CDplayer is a separate unit.  My questions is regarding the display lights for the buttons on the radio.  More than half of them are out.  I cannot figure out how to dismantle the unit and / or open it to replace the lights. (therefore I also don't know what type of lights to get)  Can you help?

Answer
Pete,
The lamps that you need are 12 volt 50 to 80 ma. They are mini lamps that you can purchase at most electronic supply outlets. These lamps are soldered in place. The face plate assembly will be held in place with several screws, after the face plate is removed the front panel circuit board will need to be taken out to gain access to the lamps.
