NAA rear axle same as 8N?

Is a NAA rear axle the same as an 8N axle? I got a new axle for a NAA and I had to grind a little off the spline thickness to get it to go into the differential. When I ordered the axle I was led to believe the NAA and 8N shared the same rear axle. I thought I had better check with you guys before I go any farther just in case there is a difference. The base of the splines on the new axle was about .015 thicker than the factory axle that came out. Is this what I can expect from the land of almost right? I know the hand grinding I did is not nearly as accurate as it could be and it has me a little concerned.

Late 8N with the dual seals and the NAA axle will interchange.

That's first hand knowledge. I put an 8N axle in a Jubilee.

The earlier 8N's only had one seal and were not machined for
the inner one. Looks like most places only sell the later style now.
