22-inch Replacement Rad. for six cyl.?

i have , in the past, always upgraded any 19 " to 22" or 26" radiator. Until I tried a champion 2 core 19" in a 64 dart with a 318. That Radiator keeps the engine very cool and I never have a problem with it. The only issue i had was the install. it sits t ohigh up on the core support I had to notch the holes to get the radiator to sit lower.

you will not need the 4 core version, just get the 2 core.
