My wife bought our Unimog 1300L (435 115) from a German company here in Angola with all the material they had and wanted to get rid of, so I came into possession of 20 brake discs, which is too many for a spare. I don't know if they fit your Unimog and I don't know how much it costs to ship them from Luanda to Windhoek. Maybe we will go to Windhoek to spend the Christmas vacations.
Greetings from Luanda
