In dealing with Ford radios, there are 5 alpha-numeric characters stamped on the case, with the first and the third characters sometimes being blank!
Therefore, you have to look at the whole sequence to decode it since the the blank character is simply skipped and the sequence is collapsed. Wonderful!
Ford (and other manufactures) appear to have used this radio numbering system from 1960 to 1973, sometimes changing the position of characters! More wonderful!
Note that not all Ford radio characters (like full size car radio features) are present in the decode chart, although I've listed a few odd balls entries.
First char= Radio Style
Second Char= Year
Third Char= Amplification Style
Fourth Char = Manufacturer
Fifth Char= Car line
Radio Style
Blank=Standard Radio
C=Canadian Philips (not used in Mustangs, but used for other models)
F=AM/FM Radio
T=AM/8Track
E=electric antenna (not used in Mustangs, but used for other models)
Year
1960 through early 70s Ford uses last digit of year
Amplification Style
Digit=Number of tubes (pre 63)
[blank] =Character totally missing (68 - up)
T=Transistor
S=Silicon Transistors
Maufacturer
P=Philco
M=Motorola
B=Bendix
Car line
Z=Mustang
F=full-size Ford
M=Mercury
T=Truck
S=Thunderbird
D=Falcon
Examples:
04MD
Blank | 1960 | 4 Tube | Motorola | Falcon
4TBZ
Blank | 1964 | Transistor | Bendix | Mustang
F6TBZ
AM/FM | 1966 |Transistor | Bendix | Mustang

T8MZ
AM/8 Track Tape | 1968 | Blank | Motorola | Mustang
9FBZ
In 1969, Bendix went off the rails and the Transistor entry was deemed nonsensical (it appears). In its place the Radio Style appears there. Worse still a 9FBZ could be either an AM or AM/FM radio with an A suffix used to indicate AM/FM, according to some Bendix literature.
This format appears through 1973 (for Mustang).
There is another sequence for Ford style part numbers, not addressed in this thread.
