SLK320 Diff. Upgrade Question 3.69-1
 

BergWerks offers an upgraded differential gear change for the SLK320 R170 of 3:69-1 in which they replace the whole pumpkin. I have been trying to find the same corresponding pumpkin they are using and am not sure if I found the correct one.

Does anyone know if th ML320 uses the same diff. as the SLK320 ? If not, which 3;69-1 ratio diff. shares with the SLK320 ?
