In my 76 I have no audio at all. Could anybody give me a list of stuff I will need to go back original? I ordered a delco radio but have no experience installing. If you could be precise with parts I need to buy for rear and front assembly and hook up. Thanks guys but I haven't any clue bout this! I'm not sure if I need insulation covers for the rear speakers the brackets what all do I need to hook it up correctly?
