Radio antenna

The similarities between my 90 D150 series pickup and 75 Duster is that both antennas interchange on the mast. Both antennas are identical. I’m pretty sure the antenna base bolt on the mount didn’t change size through many years. Not sure about a Baracuda. A salvage yard sourced base off a truck as late as 93 may get you close to your goal while using factory stuff. Just an idea to keep it Mopar.
