I put a Champion radiator in my wagon. The radiator sat too high and too far forward. (towards the engine) The hood touched the rad cap when closed, and there was no room for the fan.
I slotted the mounting holes by about 1/2 - 3/4 inch to get the radiator down so the cap didn't touch the hood. I tossed the flex fan that was on the car and used a stock fan, and a 1/2 inch spacer to get the fan to clear the radiator. I should have cut the mounts off the sides and had them rewelded in the correct position, but I was in a hurry to get the car back on the road.
My wagon is a /6, but you may have similar fitment issues with the Champion radiator.
