I got my new stubby antenna in and decided to put it on. Well when I went to take my antenna off the stud broke from rust.
Now I'm trying to get this chrome piece off with the notches. It won't budge.
I fear the rust has set in under it freezing it up. I sprayed WD-40 on it and I assume it just screws off like a nut? Any suggestions?
