Thanks for looking that up, I saw the PM showed the exact same replacement #. It seems odd that the ratio's that year are the same, I was wondering if anyone knew why they were?? What prompted the change later on? The reason is that I am still trying to find a decent 603.912 N/A to put in my 300E and would love to know what ratios were in the Euro diesels, manny or auto for the 300D and 250D? Anyone with experience driving any of the above, please post. The W124 250D especially is a popular taxi, and would think that the factory ratio would be well over 3.07 to carry the weight.... Thanks!
