Your radio actually decodes as a 70 full-size model, not Chevelle. You can verify this here:

Yes I know it does. Same exact radio though. I matched it up to a 70 Chevelle AM radio I sold a few months back. It was an exact match, minus the tag info.

And that would be misleading.

[Fast67VelleN2O]

How am I being misleading? I state it fits Chevelle, Camaro, Nova and Impala and show a picture of the tag? I don't understand your comment as to how I am misleading anyone.

[mockingbird812]

Your implication is that it is CORRECT for the application of "70 Chevelle, Nova, Camaro, Impala". Perhaps you didn't mean that, but that is my take on it.

Your ebay ad even implies it stronger:

"Here is a super nice original green tint radio for a 1970 Chevelle, Nova, Camaro or Impala. "

His description is fine.
This particular radio was interchangeable and shared with other vehicles in 1970.I can personally attest to that,but here is a indepth explanation as to why.


01APB1 is split up into numbers and letters that reveal the application.

0 indicates the last digit of the model year: 1970

1 indicates the GM vehicle division: 1 = Chevrolet division. (2=Pontiac, 3=Oldsmobile, etc).

A indicates the vehicle: "A-body". (mid-sized vehicle--Chevelle)

PB indicates the type of audio equipment: PB = AM pushbutton radio. (FP = AM/FM pushbutton, FM = AM/FM-stereo pushbutton, MP = Multiplex adapter, etc).

1 indicates this piece of audio equipment was apart of the first design run. This really isn't that important compared to the rest of the model number. If "2" had been the last digit, it would simply indicate Delco had made a change in the production of the same radio (such as an electronic circuit board revision) and it would have been apart of the second design run.



Therefore, the above radio is a 1970 AM pushbutton model originally installed in a mid-size Chevy. (It would be correct for a 1970 Chevelle, El Camino or Monte Carlo).


BE CAREFUL--there's some important exceptions:

Example: the correct model number for a 1969 Chevelle AM/FM pushbutton radio is: 91BFP1.



Using the decoding information from above, you might be confused by the "B" in the model number since "B" indicates "B-body" or in other words, a full-sized Chevy. So why is it correct for a Chevelle or mid-size "A-body" ? The answer is some of the same audio equipment was shared among different Chevrolet vehicle lines. A full-size (or B-body) Chevy such as a 1969 Impala shared the same AM/FM mono radio with such vehicles as the Camaro and the Chevelle. To keep things simple and costs down, B-body radios such as the AM/FMs were often installed in other vehicles. "B" can also be thought of as the "default" radio to be installed when a vehicle line did not have its very own line of radios. In fact, many Chevrolet vehicles "borrowed" B-body audio equipment at different times in production.

When important design changes were made to a vehicle line or the radios themselves, that vehicle's radio could no longer be "shared" with other vehicles. That's why a 1971 mid-size AM/FM mono radio has its "own" radio with a service model number of 11AFP1 because the 1971 full-size AM/FM mono radio with a service model number of 11BFP1 was no longer interchangable.

Thanks Rick!

Rick - reread the explanation that you cut and pasted from Chevelles.com and you'll see that your conclusion is not correct. As quoted above, The B radio was the default when a vehicle line did not have its very own line of radios, as in 69. In 1970 as in 71 there was a separate line of A body radios with their own number. As explained further down, That's why a 1971 mid-size AM/FM mono radio has its "own" radio with a service model number of 11AFP1 because the 1971 full-size AM/FM mono radio with a service model number of 11BFP1 was no longer interchangable.

So a unique service model number was given to a radio when the default radio was no longer interchangeable. That is exactly the case in the 1970 radios.
