Cold case is owned by the original owner of Year One, he has also been a big Pontiac guy. His rads should fit pretty good..
What I did with our original Harrisson rad was, I filled it with Vinegar and let it sit for 24 hrs and then flushed it with tons of water, worked great. it was loaded with white build up and that cleaned it out good.
