I have googled, looked on amazon, ebay, crutchfield, searched the forum, these things used to be easy to find, nobody seems to have an antenna adapter for 1978 chevy to new style radio. Does anybody know where I can find such a beast or have a part number to help in my search. I want to take the car to the drive in this summer with the new sound system and need the antenna to work. Thanks in advance guys.
