Default C3 Radios

Not sure if I should have posted this in general or tech... but I was wondering if anyone knew what the model numbers or part numbers of radios for C3s were. I need a stock radio for my 73, not sure if I care if it's AMFM or AMFM stereo, but it would be handy if I had some information to determine which I was asking for.

Default radio codes

got this off a ebay listing when I was looking for a radio. Hope it helps.


Sevice model # for this radio is : 11VFP1

The first digit is the model year of the radio 0=1970. So 8=1968, 9=1969, 0=1970, 1=1971, 2=1972 3=1973, 4=1974, 5=1975 The second digit is the car line:
1 = Chevrolet
2 = Pontiac
3 = Oldsmobile
4 = Buick
5 = Cadillac
6 = GMC
The third element is a letter which corresponds to the fisher body style the radio goes in:
A - Midsized: Tempest,Chevelle,Camaro,ChevyII,Acadian
B - Fullsized model: Bonneville etc.
C - More than full sized: Cadillac Fleetwood.
D - Rear control: Cadillac 75
E - Toronado, Riviera
F - Pony car: Firebird etc.
G - Grand Prix etc.
H - Subcompact: Sunbird etc.
L - Opel
T - Truck
TTC - GMC truck tilt cab
V - Corvette
X - Compact: Nova etc.
Z - Corvair etc.
The next two letters indicate the type of radio:
PB - Push Button AM
FP - AM/FM mono
FM - AM/FM~Stereo
K - Fader Control
MP - FM Multiplex adapter (second part of a two-piece radio)
TZ - Stereo Tape Player (8-track)
RV - Reverberation Amplifier
FW - AM/FM/Weather band
MW - AM/FM~Stereo/Weather band
In 1970, integrated AM and AM/FM~Stereo/8 tracks became available which added a third letter - T or "AMT" or "FMT" In 1970 there where a lot of AM - 8 track combos sold, FM stations were still a rarity in parts of the country.
Finally there may be a digit (1, 2) on the end which indicates a running change or revision number.
About the ultimate was reached in the late 1970s with the model xxBFTC1 - An AM/FM~Stereo/8 track/CB unit in three pieces - the radio unit which went in the normal dash position, a CB unit which contained the transceiver electronics, and a control head/microphone.
