Well, not exactly a screw loose (although some might disagree with that), I'm actually missing a screw. Specifically the one in the door panel behind the grip. I have a 2003 Tahoe LT and I was replacing the power window/door lock switch panel and notices I'm missing a screw in the door panel. It's not a big deal, but I'd like to replace it. Does anyone know the specs of that screw so I can find a suitable replacement?
