The factory AM, AM/FM, and the tape deck/AM radios all fit into the same dashboard mounting face plate. And they also fit the factory console face plate (although that was not used on any 67 Shelby).
Of course, it is worth mentioning, the the standard - most installed radio in a 67 Shelby was the AM radio.
There is no difference between the standard interior face plate, and the deluxe interior face plate that these radios fasten to.
