 What do you mean by "off about 10 deg".  Does that mean the angle of the
 flange does not match the spinner?  I fly an RV-8 with a Hartzell.  As I
 recall, the front bulkhead can be spaced forward with washers a little
 to make the fit.  I don't recall any adjustment using the front cap.  In
 any event call RV or use the RV mail list...lots of good folks there.

  The spinner has both a front and back bulkhead.  The rear one
 indexed well and lined up with the prop.  However, the front one was off
 by about 10 deg.  It is held to the prop hub with 4 bolts on the front
 cap.  From the diagrams in the book it looks like the center bolt and
 nut can be loosened and the cap rotated to allow the bulkhead to align
 with the spinner.  Is this the case?
