Bcuda AM/FM is unique as is says made by Plymouth or Plymouth Division on the face.
Not sure why u think $400 is outrageous?? That is a price from 10 years or more ago. I recently sold a '69 Dart AM/FM for $750. AM/FM's are very rare to find these days!!!!
I also have a '69 Bcuda AM/FM that i'd likely sell.......if my friend davescuda doesn't have one.....( i was going to add it to one of my BB 4spd notch cars, but that car may never be restored by me?)
