 Thinking back many years to my first J-H that had issues with overheating in our hot Midwest summers so I'm thinking about replacing the original one on my new-to-me '74 MKII before it's get nasty hot here in SW Missouri. I found this one on Amazon for only $180. Has anyone installed one of these? Looks like a Champion for less money.

 Your first J/H likely still had it's original two row radiator, switching to a three row radiator will solve your overheating problem. When I got my J/H in '93 it still had the two row and it overheated on hot days and in stop and go traffic. I switched to a three row and have had no overheating problems since. I got got mine (brass) from Delta around '94 or '95 I don't recall what it cost. For $180 what have you got to lose.

 Just ordered one, it looks like and has the same dimensions as the Champion radiator and is TIG welded. I'll let everyone know how it fits and performs.
