74 360 torque converter help

Hey guys I recently purchased a 1974 360 to install in my dart but it didn’t come with the torque converter and I did hear that I need to make sure I find the right one. Does anyone know which one I need I have a 727 trans that is already in the car
Thank you
You can buy a external balanced flex plate and use a 727 converter without the weights attached or you can use a regular flex plate and use a 727 that’s weighted correctly.
