Radiator clearance help

Im restoring a 66 Barracuda and put a ,73 360 in it. The car had no rad when I bought it. I purchased a Champion rad CC526 to install. I had seen another member use the same one. When I put the rad in, I only have 2.5-3 inches clearance. Im looking at running a solid fan with small spacer. Im kinda at a loss. Any suggestions appreciated.

Thanks, Tim
