318 Flex plate question/ help

First I want to apologize, I just went to the video again and 66valiant is correct. It was a 360 and not a 318. I do really appreciate your quick responses and input. Thanks for y’alls help. I knew you guys would set me right and guide me in the right direction.
Again sorry, I wish I would of paid more attention to the info on the video description.
Thanks for your time and your responses where informative.
Thanks
Dan
