A/C Removed...now what?

Years ago, the PO removed the A/C from my 71 Swinger. In doing so, he also removed the vents below the dash and left this ugly monstrosity. I have lived with it up until now, since I am redoing the car, I want to figure out how to make this look a bit better. Functioning A/C is not an issue, I just want to know how to make this look better.

Is it possible to remove this part of the unit and leave the heater, or is this an all in one unit? How about some kind of cover for this? Looking for suggestions.

Thanks in advance!
