Hi, i am looking to replace the rear output shaft (part that goes from the differential to the wheel) on my 2003 bmw z4 e85 2.5i manual transmission. however i am encountering a problem with finding the right one. i ordered part number 33211229708 from ECS tuning and it did not look like the one that came off of my bmw. on the one from ECS tuning, the flex plate or bushing (the part between the two plates that attach to the differential) is much wider than the one on my bmw (the two covering plates are almost touching).
the one off of my bmw

i was wondering if anyone knows the difference and could help me locate the exact part i need as i am unable to fit the one from ECS tuning on my vehicle.
Thank you all for your help.
