What a blast from the past! This new old stock Motorola automatic control head AM radio is ready to use in any 1942, 46, 47, or 48 Chevrolet. Just like it came from the factory, it features the harness plug and the original box. The box says it is model number 8CTA and is interchangeable with 6CTA – D921. The label also states this control head cannot be used with a Motorola radio manufactured prior to 1945. The radio has been in this original box for many years. It could use a quick buff before installing it in your Chevrolet car. The box features multiple bends and tape residue. While we cannot test this item, it would be perfect to install it in your vehicle or just put it on the shelf of your parts rack on display. 20889-OP
