Well, I've been pondering this idea lately for my build and believe I am headed this direction. Once April hits, I plan to buy a radiator, split it, and re-weld them to in the front fenders. I may still need a center radiator like Mitch has, but since they will be in series, its should be pretty good for cooling with fans. Thought you guys may be thinking the same thing. Here's the writeup for the idea:
