I can't confirm the NR740BB fits a DC0040 cutout. The NR740 is discontinued, and the Norcold DC740 replaces it.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
