This came out of my 1966 Dodge Polara when I upgraded to an AM/FM radio.
It will fit 65-66 Furys, Polaras Monacos, Newports , 300s, and New Yorkers.
Should also fit several other applications also.
Here is a good site to see what radio fits what car. Identifying Car Radios
It was working perfectly up to the day I took it out.
It is very low in height and will fit models where the heater controls are directly above the radio.
