Adapter. Just made from aluminum.

Because of the Eaton's unique inlet the inlet pipe cannot be simply flipped over. It is semi-circular on top, triangular on bottom.
I traced both sides on graph paper a few times, took some measurements and superimposed the inlet, upside down, on the blower inlet trace to get the shape of the adapter needed so it would seal both sides.

The adapter seals to the blower and the flipped inlet seals to the adapter.

There is a slight loss of airflow because of this, and it probably introduces some turbulence, but I'm not concerned (I don't care if it robs some power, it is still going to be a major improvement)
