    Nope, the crankshaft snouts are the same.  I recently put a Spica crank in a Bosch engine.  Only the pulley and nut seem to differ in my experience and they seem interchangeable both was.
    Interesting that the early Euro cars had the open nut accepting a 36 mm socket.  The Bosch cars definitely went back to that.  So I guess my earlier statement that if you can see the threads on the end of the crank, it will take a 36 mm socket.  It not, then it is 38 mm.

     And, yes, I am way behind in my reading.  As I am off to race the new track near Omaha this weekend, I may just have to skip a week's worth of digests.  And then there is the two weeks I will spend Californicating in early July...
