An overflowing ice maker usually means the water valve isn't shutting off completely. The single-port valve for fridges without a water dispenser is now the 640908, which replaced the 637580, and it's discontinued. Before you replace anything, check for high water pressure (a pressure regulator helps). Email info@rvfridgeguys.com and we'll check what's available.
