Yes the ball diff came with it's own outdrives.

They differ from the standard m05 ones by being splined as opposed to flattened off.

I've had ball diffs in other cars and the outdrives are part of the diff plates, they are more akin to standard outdrives in the TA-03 ball diff.

One outdrive has a long pin at the end which runs through the diff, out the other side and into the other outdrive. It's as if they are designed to slide left and right within the diff splines.
