will 913f shaft fir 915f head

Don't think so. I'm fairly sure that only the driver shafts are interchangeable between the 915's and the old 910/913 drivers.
 
The fairway adapter changed from the 910 to the 913. In the 910 the adapter was the same as the driver one, but they made it smaller in the 913 fairway. Pretty sure a 913 fairway adapter will fit in a 915 fairway but will not fit in a 910 fairway.

The driver shafts are interchangeable all the way from 910 to 915, as others have said.
