all parts were not included.  Had to purchase parts directly from Delta.
Should have received credit from Wayfair.  Never received.  The handheld can only be mounted on the left side. The diverter doesn't allow it to be mounted on the right.  The instructions are misleading and make you believe that it can be mounted on right.  Again, another component, 6 way diverter, had to be purchased to allow handheld to be mounted on the right.  Frustrating.
