Has anyone purchased the brass and copper radiator offered from radiators.com ? It shows it is a original like construction but doesn't clearly state it is a 4 core radiator. Mine hasn't started to leak but I see some signs that it appears they will be coming soon. With all the work I am doing to my motor and changing the A/C system I hate to have to pull the radiator out again because it sprang a leak. I looked at the champion too, it is about half price but I have heard a lot of good and a lot of bad about them. From reading it sounds like the aluminum doesn't hold up if you have any play in the radiator core support. My core support looks really good not much rust but I am not sure if I want to take the chance on the aluminum.
