E30 325i Rag-Top 2914 Report post Posted October 6, 2015 Looks to be a medium case, count the number of bolts holding the backing plate on. Quote Share this post Link to post Share on other sites

E30 325i Rag-Top 2914 Report post Posted October 7, 2015 Yup then that is a medium case, not a small case. small has 6 bolts on the cover, 8 bolts on medium case. 1 Quote Share this post Link to post Share on other sites
HamishNZ 1 Report post Posted October 8, 2015 Ahh thanks. I was wondering why it's so different from the medium case E34 525i diffs I have. The mounting is completely different but I assume the internals are interchangeable. Quote Share this post Link to post Share on other sites
