The CC radiators have a very fat core (3" on the one you linked to) so you may have problems with clearance between the core and water pump snout. I sure did, and had to go to a Champion radiator which has a 2.5 core thickness.
Do you know if the brackets are welded to the Cold Case radiator so it positions the core way off the core support like the Champion radiator? Seems like if they welded the brackets on correctly, the extra 1/2" in thickness may not cause any issues.
