All of the Audi 4000Q stuff is pretty much NLA now as well. Ask the UrQ guys about parts availability, they are hating the fact the factory has stopped supporting their Q's.
The syncro was to have used a fluid based system if memory serves me much like the torsen system.
I have had a 2 4000csq one was a calloway car lots of fun the other was a 5K turbo swap and that was better. I had some 2Bennett stuff and a Stebro on it. Electrics sucked but can be fixed, Audifans for the list group for old 5 cylinder stuff and repair info.
