The WV/Audi jeep has a VW engine and that's about all I know. I believe the VW syncro system post dates their introduction so I suspect the trans-axle and differentials are Audi. One poster (in Denver) on a VW forum has one and claims to be at his wits' end trying to match part numbers. I think he's a WV only guy so he might not be looking in the right place. You do have access to the VW/Audi dealer parts inventory system, eh?
ETKA? Yes, I’ve got a version running.
And you’re a LOT more serious than I - but I have done a CV axle recently, have done suspensions and timing belts, and have a small lift in my 2 car suburban garage.
I’ll have to look around for the name of this thing, and see if its in ETKA.
