My Corvette(s): 1979 L82 Coupe dark brown metallic
No. I don't have a CB option in my 79, but I do have the factory power antenna, which broke some time ago. I searched all the swap meets for a working used one for a long time and even find one, that I thought worked, but it too was not functioning too well. Shame on the seller. I ended up buying the AC Delco replacement model and modified it to fit on the 79. It's perfect. To this day, I don't see any power antenna's for sale at the swap meets.
If your looking for a CB radio for you vette,stop ay any truck stop,eg,T/A,Petro,Pilot, they usually have the best selection for radios,antennas and acc., for what you are looking for!!!hope this helps!
