Thanks guys. Nice work on the Polara. I have less than 1/2" from the radiator support to under the hood. No good path for airflow there (for me).

This seemed to be the best solution for maintaining a stock look. (and I was always impressed by the amount of airflow from the interior vent ducts when open)


The radiator duct concerns you? Pretty similar to what a lot of newer cars have from the factory and it sits right at thermostat temp in any weather.
