The M9 Q1Q2 "foot" plate (TB23363) has been installed over the floor plate.  A nominal gap between the plates of 1/2" was set before lowering the plate, it was then leveled using the three adjustment bolts resulting in a larger gap.  After leveling, the plate was lifted to remove the spirit levels and lock the position of the leveling bolts.  The plate was then re-lowered and the tiedown bolt assemblies (TB23383) were installed using 50ft*lbf of torque (about the maximum practical amount with standard 20' pole tools)
