I have a 2004 Silverado 2500HD. I just replaced the stepper motors for the gauges. I need the part number or a place to get the solder in bulbs for the gauge lights. The kit I bought has the push in LED bulbs. I need the solder bulbs (I do not want to replace with LED'*).
I doubt you will find a GM part number for those bulbs. Mainly because they are not user replaceable. Instead, take one to Radioshack and look in the 12v bulb section and see if you can find one close to it.
