Based on images I can find I see that the 2020 Grand Design Momentum 376TH comes with a MORryde Cushioned 5th Wheel Pin Box for 18K to 23K Trailers # MR24VR. You can verify this by looking at the tag on the front left of your pin box where it should say RPB72-1621SHD. If this is what you have you can use the Curt Flex Air 5th Wheel Pin Box # LC369535 you found.

If you have a different pin box please let me know the information on the tag or if there isn't a tag you should be able to find the Lippert Frame tag above on the mounting arms which I can use to determine exactly what pin box bolt pattern was installed.
