Tony,

The original PN was 116 032 02 71. Superseded by 116 032 06 71.
The original bolt was necked and was tightened by the angle-of-rotation method.
The present bolt is full threaded and is tightened to 85-90 ft/lbs (lubricated).

In your parts gathering expeditions did you acquire any bolts from the 560 crankshafts?
They are the correct ones!
