Does anyone know the difference between the two part numbers listed in my manual for the NXA.

13121 - NX4 - 811 and 13121 - NX5 - 701? Seems wierd they should list two part numbers. I have some of each in stock but can you mix and match or is one better than the other.

Honda replaced the NX5 ring with the NX4 ring. The NX4 part number you have is the latest ring.
