VPI VTA Base question


Does anyone know how to tell the difference between VPI's current JMW VTA base, and the 12" Unipivot Base?  Something visual? Or measurements? 

I can't achieve the proper alignment with my 10" Fatboy arm and want to make sure I got the correct base.

,,just a silly question.....are you sure you have the pivot spike on the proper pivot.   I know If not careful, I can move my arm to another spot.   The correct spot has a metal insert and properly set up will allow the arm to tilt (azimuth) easily
