Flex plate and converter

The engine was internally balanced at a machine shop. Balancer is supposed to be correct. He also had the flex plate. But I got the converter later. I think I just need the correct flex plate, but don’t know which one. Also if the converter has a weight on it, I need to just remove it? I am hurt at this time and can’t take it apart to see exactly what I have. But I would order the correct flex plate if I knew. Thanks
