These roof ducts are very similar to the ones used by Cadillac, Buick and Oldsmobile for their factory air conditioned sedans in 1953-55. Hardtops did not have the roof ducts. Interestingly, Cadillac continued this for 1956, when Buick and the other GM divisions went to a front mounted air conditioner, as Packard had in 1955.
