Dave and Doug, the dimensions depend on the size your replica is between the headlight housings, etc. My radiator is a brass 4-core, triple pass and is probably at a 40 degree angle spreading fully across the opening. I was afraid the air was bouncing off the rad and flowing under the car so I put some ABS plastic on the "floor" of the frame in front to force more air through. This topped off my cooling mods and the car stays at 180F even when it's really hot out.
