I am doing some work on my 70 Nova and started to think it was radio delete. I have the top half of the trim broadcast sheet, and there is no code for the am/fm that is in the car. Also, it is clear that someone did some amateur wiring when installing the radio. What is baffling is the fact that I have a correctly date coded windshield with the antenna in the glass. Also appears to have a a factory speaker. How can one be sure of the original build?
