Hi All,

Several years ago, my mechanic rebooted the CV axles on my 1984 300D. Part of the deal was that he had a 1985 differential that was just sitting and I was able to get that put back in my car when he pulled my diff. Right now, it looks like my speedometer is off by a few mph at lower speeds and up to about 10mph at freeway speeds. I am wondering if the speedometer needs to be matched to the 1985 differential. Is it possible to buy a 1985-specific speedometer or match my gearing? It would seem the easiest way would be to get a 1985 speedometer. Does anyone have one for sale or know where I can buy one?

Thanks,

Dkr.
