Shark fin Antenna (check yours)
 

My Shark fin Antenna is lose. I pulled the headliner down turned the bolt as much as it could go and it’s still lose. It won’t tighten anymore. Any ideas ? Gaskets ? Something I could use as a better seal? It’s only like a quarter inch gap or less.

1/4" gap sounds huge!

im about to pull my shark fin this weekend to wrap the roof, i will check it out then.

When you say pull down the headliner, did you just pull from the rear of the headliner or took panels apart to drop the whole headliner?
