The first two photos show the partition dry fit into the air box. You can see the stops added to the out side of the plenum to attach the top of the partition and the six holes for the vacuum motors. Also you can see the fascias on the toe kick and the back. These will support leveling feet and increase the stiffness of the bottom.
The last photo shows one of the six vacuum motors to be mounted to the partition. Before i attach the partition, i'll install the air motors and wire them.
