Hi Quick question. I have a billet crankshaft that i'm led to belive is a billet BMW V/12 shaft, but the main sizes do not corrispond to the road going V/12 sizes (M70-M73-S70 75.0mm) The size of the mains on my shaft are 58.0mm with a 24.5mm thrust width. Can anyone tell or help me find out what model it's from.... I can send pictures via e-mail Thanks Cameron
