The Henry J radio certainly fits and looks correct in the Darrin but when looking up accessories for the Darrin the only thing that shows up is the heater, wire spoke wheel covers, safety belt and exhaust deflector. There is no listing in the Darrin parts book for a radio under accessories and the sales literature does not list a radio either. The Darrin's came from the factory with turn signals, shaded windshield, windshield wings, electric windshield wipers, 5 whitewall tires, stainless steel wheel covers, exhaust deflector, bumper guards and cigar lighter. That info was in Kaiser Willys Trade Letter KW53-2. None of the factory photos of Darrin's have an antenna and there seems to be nothing published about where to place the antenna. Does anyone have other info on Darrin radios?
