It's a non-retractable antenna, I'm not sure how it looks like under the base, about the wire. Is it hard to remove and change ? I might order a real complete kit, from Rick's Camaro. But the bottom end of the antenna, is not like the ones on the picture. It's flat, without the lining we see on this picture.
To remove the base, I believe we have to access it from inside the wheel fender ?
