Identify year of Radiator?

So my rad is 22" wide I read somewhere that the Max Cool rads were 26" wide. If this is correct was the radiator support wider in a bodies with Max cool because some of the cooling lines in a 26" wide radiator would be behind the rad support, unless it was opened wider?

It's not correct for '67 through '69.

(Nor is it easy to convert to a 26" wide radiator. Go ask @Rob_Mopar if you want the long version. )

Here's what Chrysler did for A/C cars in '68.
Its needs the full package. The pulley diameters, the water pump impeller are just as important as the fan and fan shroud.
