XM antenna replacement
 

Good afternoon I just purchased a 2005 SS from the original owner who bought it brand new says he never did anything to it the radios factory the antenna is a factory XM antenna. He said he never changed it but antenna. Part is broken and I’ve been trying to find a replacement and I found nothing. I found the one that screws in but this one has two little star screws and you unscrew those and pull the antenna out. I can’t find that anywhere. Can anyone help me with this?

Those things were hard to find (impossible almost) about 5 years ago when I had to find one. I ended up needing to go to the junk yard for it.
