Some Mopars did have quarter mounted antennas. My old '64 300K had the power antenna mounted there.
With that said, I eliminated the antenna hole in the Barracuda for a cleaner look. I bought a small powered antenna off Amazon, but I haven't had a chance to try it out yet. The GTS will retain a correct factory antenna. No car covers needed as both cars will be garage kept when I get the new garage finished.
