I found a vintage semi-automatic antenna to replace the missing unit in my car. What's challenging is that the antenna is pretty long, and hits the base where the ECU and Thermocouple plate that's mounted on the passenger side. There is almost no room to mount the antenna unless it's at an angle which then doesn't look right. Did the cabrio cars or ECU cars use a different antenna? Or is there a mounting trick that I'm missing. Thanks!
