Hello, I have what I hope is a dumb question! I have a 68 GTO, however the antenna may be an aftermarket. The mast is an oval shape and it slides nicely onto the post, which is about 1 inch. The problem is that it does not attach hard to it, I was wondering, does anybody know, how the mast stays attached to the post? I’m thinking of a small spot weld, but feel like I’m missing something. Thanks!
