Cracked 360 Magnum Flexplate

Yea I hear you pishta. The 360 balance it a PITA. I just had a idea. Why can't he take the weight off the flex plate he has and weld them on a new neutral flex plate? We used to do that to torque convertors back in the day. Hell I remember Ma Mopar sold the weights as a kit. Don't think it would have to be SFI approved as he is running a stock flex plate now.
