Here's a link to a picture of it as a parts diagram.https://www.niemoeller.de/en/w108/w108/B057/24

You can call Alfano Motors, locally, and see what's available through MBZ. It takes special MBZ sockets to get one apart.

There's a complete axle on ebay, down in Valencia, but IMO, ridiculously priced. You might be better off sourcing from a wrecking yard on your own, or buying a donor car that's in bad shape.
