well..... my immediate thought is eliminate the 2 holes... then i was think of making 2 full length, rectangular ports at the bottom front, and top front edge... with a "tabbed" edge.. that i can fit, and screw a fiberglass piece to..
kinda like where i marked it out in paint here, top and bottom...
they have to stay over on that side of the box, on that side of the heater core... i'm thinking i may just cut off that whole sidewall with the 2 holes and put a new full piece in that extends top and bottom, to form that wall of the output tabs....
