Will try this here

Lining up the parts for my summer project. I plan to install a dct into my e36 track car. This will require custom drive shaft work (I think). Question I have is, does anyone know the spline counts of the BMW drive shafts? Specifically I want to couple the front off the 2011-13 135i dct shaft with the rear of the e36 shaft. This still has to be shortened but some work needs to be done regardless. Just trying to figure what.
Thanks!
