i am new in this post and call from germany? sorry about my english it is not so good
Just get the complete rear achs with side shaft, differential brakes... but dont have the driveshaft.
few weeks ago we change the differential from a bmw wich has a different head for the driveshaft. we change the old head to the new head, now the driveshaft fits to the car.
maybe i can put the head from the 335ia to the m3 differential? is it possibel? a new driveshaft is very expensive
