How does one replace the dashboard light in a 1983 MB 300TD?

The lights around in the speedometer cluster are changed by pulling the cluster forward. There is a special tool to make this easier and to not damage the dash, but I always removed the kick panel on the driver's side and reached up underneath and gently, but firmly pushed it out. Once out, remove the speedo cable and wiring harness and you can remove the whole cluster by guiding it around the steering wheel. The lights on the center switches (sunroof etc are all lighted by one light fed through fiber optic cable from behind the heater control switches.
