I tried to replace mine. Would not cooperate so I just put a fixed universal black antenna on it. Works great! Only downside is I have two buttons on my dash that dont do anything and I have to unscrew it before driving through a car wash.
Yeah....that's what I'm doing. Going to put an AM/FM/CB splitter in. Where did you get the wrench to remove the nut on top of the fender? No one seems to carry them locally. I should have asked Walcott CB if they had one when I ordered my stuff.
Edit: I'll have to see if I can remove those buttons and score another blank fill piece to put in there.
