Sorry, must have been in a fog when I typed that.
Yes, we sell only one stub axle, they are both the same length and they fit both CLSD or Torsen diffs.
I think your confusion may be that the R160 VLSD requires a longer spline on one stub axle, not the case for the R180 CLSD or Torsen.
Just to add my experience.
I have the Torsen diff in my 510 from an 09 STI, it does an excellent job of putting power down to both wheels equally which makes my car dig great off the line, I have noticed the behavior of the Torsen can be quite scary under power through a turn, because it likes to bust both wheels loose at the exact same moment, without any warning! The Clutch type LSD gives you a bit more warning and is easier to tame and offers some adjustments, but not as quick to react. My car makes 380whp and is mostly used in a straight line on freeway onramps so the Torsen was a good fit for my car.
By the way, any R160 VLSD from a Subaru MY2000 or newer will have an updated style VLSD that 510 stubs will bolt right in as long as you swap the buttons over into the side gears from the old Datsun R160. These VLSD can be found standard in any 2000+ Outback with cold weather package in 4.4 ratio in the automatic and 4.1 in the manual. only $50 at the salvage yard.
