69 Dart 340 GTS Radiator

I've discovered the radiator in my Dart is too small for the #'s matching 340 in the car. Does anyone have a 340 Radiator....I believe 22 inches wide for the 69 Dart?

Does the GTS have a special radiator for the 340 cars?

I don't need the exact year/production code....just looking for the stock appearance Vs. a aluminum.

Anybody know what year radiators will all fit the 69 dart?

Thanks,

Will
