I have a 2012 FX4. Of all the mods on a truck i figured this to be the easiest installation, but anyways I bought a replacement antenna last night and thought the stock antenna would twist out just as my dads '02 did. Of course thats not the case, I dont know how it comes out? I searched the threads didnt find help and dont want to tear into my truck anymore than i need to. Has anyone else taken off their antenna and replaced it with a twist-on antenna?
