Meager progress attaching Actuators.  The first attempted V4 pulled the crossbeam down 30+ mils. Tried again with similar results.  Then a bad feeling bolt became a tap-it job followed by the bolt is galling situation.  I did get it free with copious lube and leverage.  Another attempt at attachment yielded same shift independent of fluid flow state.  I'd rather not change the Actuator so I may be in for a custom shield job.
