ti sounds as if there may be a fatigue flaw in the rear of the diff case. perhaps due to the power of the engine. i dont know what will interchange but i suspect that diffs from the 300e will fit. and the 190 16v. i suspect the ratio may be 265, right?

i think that is what my 124 body 300d was.

bad luck!
