economy for my gmc's toolboxes

Hi to everyone, I hope your vehicles are getting good milage. I've been wondering about making up and putting a couple of aluminum (maybe plastic or thin fiberglass) contoured air dams around the square fronts of my weatherguard side mount toolboxes. I mean the big flat areas can't help the airflow, right? Should I consider the rear of the toolboxes also, probably. Has anyone here done something like this? Do they sell them premade anywhere?
