Anyone change bulb/light in dash?

92 Astro needs new bulb in the dash behind the odometer/speedometer and fuelgauge side of dash. I have already replaced the bulbs in the switch to the rear ac and that was no problem. I am wondering if anyone here has replaced the bulb(s) that light up the speedometer and might give me a few pointers before I embark on this task.

This weekend I am going to takle the CPI, taking the plenum off and all. I have a good start on it by reading this forum. Thanks to all those who have responded.
