I have a '64 Malibu and am deciding whether to buy a radio that is supposed to be the correct manual tune Delco radio for my car. The only number on it is 31MBV8525 or 31MBV8535 which is listed as the identification number but that number does not match up with any of the reference material I can find. Any ideas?

Also, are the radio knobs interchangeable? If so, with what models and what years?

Thanks.
