Gauge cluster lighting problems

I bought new LED bulbs and installed them. They were way too dim. That's beside the point. Half of the lights have gone out and it's not due to bulb failure. The contacts are worn on the back of the cluster. Has anyone else had this problem? The simple solution is to buy a used gauge cluster and hope for the best. Best case scenario and the odometer will still be off. Does anyone know if it's possible to replace/swap the plastic thingy with all the electrical contacts (for lack of better terminology) from one gauge cluster to another, hence leaving the original gauges and odometer in the truck?
