yea i was also thinking about mounting a small fan somewhere in front of the gm external/auxilary cooler(also mounted in front of the radiator) but couldn find one that was slim enough to fit in between the cooler and the front-back bumper. i was thinkgin about tapping in the wires off the factory radiator fans, as well but thats still up in the air. HDRacing, let me know on what size fans you have as well as pricing as im not really want to spend alot of money on a setup like this. i think the spacing where i have mine(on the driver-side of where the middle metal support hanger lies) is approximately 10-11" wide and prolly 5-6" spacing between the cooler and the front-back bumper.
