Hi,
Can you please tell me the Buick part number of a 1969 radio speaker fader control? This was used when you had an a/m radio with the optional rear speaker.

Thank you.

 

What you are asking for is almost impossible . Your best bet ,I believe, would be to go to a place like Radio Shack with the control and see if they can come up with something close.
You could also try an electronics supplier like "Allied Electronics".
There used to be a company called , "Howard k. Sams" that sold schematics for all types of radios and the part # might be listed on the schematic diagram.
You could also try one of the car radio installer places , they just might have more info.
