What did you plug your fender antenna hole with?

Mopar had antena delete buttons on the 80's car's . I had several omni's, reliants , and pick-ups with them on, not sure if they will fit your car. They were chromed plastic buttons that had a little ball in the middle to simulate the antena down and they clipped in. I am sure with a little two faced tape you can make one work Take a walk through your local wrecking yard or check your local dealer.
