It is the same size. There is a housing that the female slides into... so technically it's a female spline attaching to a male spline but the female spline is also a male spline going into a biger female housing... haha if that makes any sense.
Since that stub-shaft spline is broke... I am just going to get a new stub shaft and throw that whol piece away. I've got a brand new (not reman) cv axle and I'll have a new stub-shaft, so hopefully I will be all set.
