The new one is just a super-diff, which is pretty common on hi-po Type 1 transaxle builds. It also is a step back from the edge.
The ZF is rare like hen's teeth. VW had them built for about 20 minutes in the early 70s (for use in the "Thing" in non-USA markets, unless I'm mistaken). I waited for more than a 18 months to find one, and snapped this one up on TheSamba as soon as it became available a few years back. I think I had to give $1500 or some such thing. Mine is worn out (as per Anthony). Stock, they came with metal discs and clutches, but there is a guy (Paul Guard) who has a rebuild kit available for them using friction discs and some other special whatnot. The mystery is if what I have will be rebuildable, as not all are.
If it is, the plan is to use the shards of the true cross ZF LSD in a future 5-speed for Project X, but that's a story for a different day.
