AC Unit in 65 Dart Parts Car

Because they were copying the B&B design, engineering costs were minimal, which allowed the systems to be sold relatively inexpensively. This in turn allowed the DFW Big 3 to go after a much larger market. While Detroit’s prewar A/C efforts targeted the upper end of the market (Cadillac, Packard, and Imperial), the DFW Big 3 aimed solidly for the fat midsection of the market. Furthermore, while the prewar efforts were obviously targeted at selling new cars, the units from the DFW Big 3 could be retrofitted to just about any car with a trunk and rear parcel shelf. This meant that everyone who owned car was a potential customer.
