I've got a 3 row Champion with trans cooler in a 50 chevy pu. Bolted right in, build quality looks very good, put about a thousand trouble free miles on it last year, just waiting for northern Illinois to thaw so I can start enjoying it again. Interesting enough, it replaced a U.S. radiator desert cooler which kept cracking the lower tank around one of the cooler fittings. (repaired 4 times) The Champion was the same money as replacing the lower tank, so I took a chance and so far so good. Luck of the draw? Someone has bad luck with a Champion and good luck with a U.S. radiator, and I have just the opposite.
