So thanks to your help I was able to remove my speedo cluster and access my bulbs. I'm curious what the part number is so I can order some new ones to replace all 4. Initially, I thought the part # was 30864008, but that is a different bulb that illuminates odometer and ambiant temp gauges. The bulbs I'm intersted in is for overall illumination of the entire cluster. There are four bulbs. Anyone know what part number they are? Pic below.
