Yes,
It's a laser pointer that's mounted within a piece of round bar which is then inserted in a simple adapter at the axle end. The laser target is the centreline of the differential; the advantage of using this is that the laser will shine through any smoke which the heating has caused in the axle.
I have used the mandrel and dummy bearings arrangement too, but it is a bit of a faff having to continually assemble/strip it all to see whether the casing is in line. A7 axles can be interesting because in my experience the hole in the hub is not always concentric with the wheel bearing seating which acts as the true reference point on any axle.
