How can I fix or replace dash gauges?

@oldturkey03 Yeah it's a 94 GMC Sierra k1500 .

Seems oil pressure gauge(which I changed few years ago/failing to start) started too be erratic, year later or so the temp gauge goes rt too hot when running a few seconds, (pump replaced years ago, coolant good and no overheat). I changed sensors/wires (two), cleaned MaP sensor, checked grounds, found one broken but had no effect when connected. Didn't replace thermostat yet but have it, my guru says it's likely gauges going, there's motors in them that die off, short of tearing things apart thus breaking clips etc, what else is good or how to take out the cluster and replace it or gauges etc on the very cheap low expense end.

Seems The air/fuel mixture due pcm being told it's running hot (which happened years ago w broker fan belt) causes choking when stopped like it's timing is off-rumbling sensation. Worried about damaging worse then already may have driving
