Anyone know how to disassemble this fender antenna?

[Gander]

I’d like to put this mount to use as a CB antenna but can’t figure out a way to disassemble it. I can see a couple spots on it where I could put a wrench but when I tried it seemed solid and I don’t want to break anything. My understanding is that this is a GM accessory and was most likely installed by the dealer when my truck was new so I’d hate to mess it up. I’ve got the windshield antenna for the am/fm but would like to put this to good use. Anyone else messed with one of these?

That big hex nut should be what holds the antenna body to the mounting bezel. It will be a fine thread pitch and might be a bit seized on there.

OK. Just wanted to know before I started turning on things too hard. There’s that large chrome hex and then further up just below the mast that little piece has 2 flats on it for a wrench. I tried turning both and neither moved at all. I’ll soak that large hex in penetrant and see if it loosens up.

The two flats are for removing the mast from the antenna body. It's likely seized as well. Trying to remove it will very likely break the little stud.

I though the goal was to just remove the antenna from the bezel, so a CB antenna could be mounted to the bezel.

Yes, the goal is to mount a CB antenna to the bezel. I need to get it apart so I can measure and make absolutely sure that what I order for it will fit. I guess I don’t even need to worry about the mast, just the hex nut to get the current antenna off the bezel. Now I just need to figure out what antenna to order. I saw a picture on here with something similar. Just need to figure out what exactly to get. I think something like this is what I’m looking for. This doesn’t use the big hex nut though.

If it were me I'd obtain the CB antenna and see what it comes with etc. It may come with its own cable in which case you can cut the existing cable and use the base parts that work with it.

1982 Chevy Cavalier antenna base is what I installed on my '82 Square. Drill two small holes on the inner lip of the fender and the larger hole in the top edge of the fender. There is your CB mount!

Sometimes it's nice to have one of these:
