Antenna

For car cover storage, all you need to do is remove the antenna mast. No need to remove the cap nut, bezel, etc. There should be a cone shaped base at the bottom of the mast. It has two, flat machined sides to it. Just use a 5/16 open end wrench and unscrew the mast from the antenna body. That is the size I have on my 70 Duster OEM antenna but the later ones may be larger.
