I got a 1969 am/fm radio for Christmas and installed it yesterday.
I previously had a 1971 am/fm which (I believe) was from a full-size Mercury. D1MA19A241 - 1FBM-AE.
It fit in my '69 but was a budget compromise for the correct radio.
If someone can use this, send me a PM. Free plus shipping cost.
The radio works - mostly. Sometimes it would not produce sound when turning it on. All buttons and knobs work, just intermittently no sound. Pigtails intact.
