no worries! the splines seemed fine when I was using it, I'll double check that as well as double check the spline count, I may have been a lil tipsy when counting them. The thing I didn't like about that axle was the axle nut threads are two different sizes (top one in the picture is the smaller diameter one) No idea why, it was like that when I got it. I think I also have a sprocket hub that I'll throw in as well.
