Bought a 3.07 to put in a friends car, with what i was told a low mileage, about 250000km (low mileage to be a 300tdt w123) dont know if the oil has been neglected, started the regular cleanup, and was about to swap the sealrings/dichtrings: A0039978347 but i left it be, it will probably run good as is, but paid about 700usd for it (supposed to be in perfect condition) but got some of them back from seller, and will see what i do with the diff.
anyhow, took some pictures and thought id share
