You need M3 half shafts, you cant use your 135i half shafts (the m3 items are also much larger in diameter thus have a higher loading capacity)

If you have a bolted diff, the quaiffe will definately be cheaper, if your diff is welded well you may break even or may well be worth considering the extra $ for the M3 diff/shafts.
Thanks for the input. Very valid points which I will think over. My 135i is still under warranty, so I may not want to "bastardize" it just yet..
