alright I have tried searching but to little avail. I really want to aquire a new rear differential with 3.46 or 3.96 gears if at all possible. 1985 300d with 340k. Anybody know what would be the most economical way of doing this. Is there a company that reproduces mercedes gears? where could I get the ideal differential? I am not against simply buying a used differential and regearing it, just a little lost being new to this particular community
