Wiki says E30 323i has medium case diff. Mine has small case diff
Mine has been changed, I know this because it has an LSD it did not have from the factory. However with the car I had a large box of original bits and looking into it for the first time in a decade or two the original open diff is small case too.
The prop shaft never looked like it had been played with from new either
The only 323i I have seen in recent years also had a small case diff.
Am I missing something?
