I am certain the rebuilds have been correct.  Mullany & Associates even rebuilt it and tested it.  They are aware of my problems and when they received the sequencer the spindle had passed through the head as if I assembled it wrong, but I hadn't.  Anna Maria and John have been very helpful and incredibly patient throughout this saga.  I call them now and say "hey...it's me..."     Kinda funny, but not really.

I took a look at the original spindle and noticed a distinct difference, besides the length, just under the top thick O-ring.  If you look at the image you'll see a larger plastic collar under the O-ring.  The shorter spindle is what is provided in the rebuild kit which also changes the top seal and top cap.  I had other issues with the rebuild kit, but I'll write something on that later.  
   
I went ahead and modified the original spindle by cutting the top so it is the same length as the replacement.  I am hoping the thick plastic collar keeps it from getting stuck in the top piece/head.  I'll install tomorrow and report the result.
   
As seen in the final image, the pressure has remained steady with the simpler water regulator.
