The 335i part of the shaft going to the gearbox is female too (near number 5 upper pict)
So now we need a double male piece similar to near number 8 upper to join both together, or maybe transform the M3 or the 335i part of the shaft in male...
We realy need pictures of GeorgeSmooth to understand how to do it. My M3 LSD is sitting in my garage for one year now
