Rad for a 65 Valiant

I put a Champion CC63DT radiator in my 64 Valiant slant six. Fit well and cools fine. Just be aware that the opening in the radiator support got larger in 1965. The radiator side shield is larger on the 65-66 radiators, than on the 63-64 radiators. part number CC6566
If this is the radiator you are considering, it is for a V-8 and will not work for a slant six. Aluminum Radiator FOR 1963-1969 Dodge MOPAR CAR Plymouth Valient V8 1963 1964 1965 1966 1967 1968 1969 and it doesn't look correct in any case. That looks like a crossflow radiator, that won't fit the opening.
