I installed my Champion radiator today. This was my second try. The first one was a real piece. The second one was nice but twisted. The dealer did not want to take it back. He told me to try twisting it back. I was leery, but figured I would give it a try. I clamped it down to steel welding table and was able to get 90% of the twist out. I then pressure tested it to make sure that it wasn't cracked. Today I installed it. I had to modify the mounting slightly. The fan shroud fit well, but needed moved up a little for my car (kesler 5 spd). Over all I am satisfied with it. If I was doing it again I would have spent the $550 for the Griffin.
