66 - 67 GTO Antenna

[goatweed]

I am looking for a good 66-67 antenna, the mast and base.

I was down at Portland swap meet and did not find any that was decent. :(

What does it look like? I've got one on my donor car, but think it's aftermarket. Is it the kind that can be manually pushed down into the fender or is it fixed to the fender? Maybe with a spring built in to keep the mast from snapping?

The more I think about it, the more I think it's an aftermarket.
