As long as the Mor Ryde pin box you have was designed to replace a 1621 Lippert pin box the Trailair Flex Air pin box part # LC369535 would fit and work well.

Most likely your MorRyde would have a part number like Mor/Ryde SPB72-1621LD which if so you can see the "1621" in the number which means the Flexair mentioned is the correct one.
