I've looked into this and you have 2 (and a half) options:

1.) Find a limited slip ZF - you can only get these used and they are hard to find and pricey.

2.) Install a locking differential from a synchro. A little less pricey.

3.) Get enough people together to convince Quaife to make a torque-biasing diferential for the Vanagon. http://www.quaifeamerica.com/

I think weddle engineering does, but last time I talked to em they only had
used ones in stock for 1200 bucks.
