1968 AM Radio question......

It is correct for 68 and 69 dart. it will fit in 68 and 69 Cuda but I'm thinking the Cuda one says Plymouth on the face plate.

There is a different mounting tab on one of them but I can't recall which is which. I have always wondered if a face plate change would allow different thumb wheel radios to work. Most C bodies I have come across have a slanted face plate.
