Was the square tubing added by the previous owner when he did his modifications? Sure don't remember seeing that on any I've taken apart.
The more I look at the pics, it looks like he kinda messed up the front sheet metal where the air box mounts. And, you'll need another air box for the driver side.
You're other option is to go to a Vintage Air heater defroster. You'll have to make a bracket or plate to mount it to. Mine is welded to the floor, though I've seen some that a plate is mounted from air opening to air opening.
