oooooh that is a rare piece.... The only way you could get that in 74 was to order the car "Special" without the radio... The funny thing is the Windshield would still have the atenna installed. They also made the radio delete plastic adapter but finding one that has no adapter is a great find. I've only seen them in the 6 cylinder 4 door cars... Not sure if they are were that configueration but definately a good find..
