Thanks for the photo! I had Lippert run the serial number from the photo, and was told that you have a Lippert 1621 pin box. The compatible Curt Flex Air cushioned pin box is part # LC328492 for an 18K or # LC369535 for a 21K capacity. However, the Andersen Ultimate 5th Wheel Connection isn't compatible with the Flex Air without using a Rotaflex lock out kit, part # 3247 which is available from Andersen. Another alternative would be to use the standard Curt, which is # LC158778 which would be compatible with your Andersen Ultimate Fifth Wheel Connection without needing the lock out kit.
