I've done this several times. You can use a flat tip or a butter knife to jimmy the gauge out. You may want to cover the end of whichever tool you use with some duct tape. I'd bring a pad of paper and draw a very clear diagram of which wire goes where before you start disconnecting wires. I would use a very thin wedge like a butter knife to get the bulb sockets out of the back of the gauge.
