318 and lock up converter Balance

5.9 balance weight is on the flex plate and LA 360-balance weight is on the convertor.
Agree, and that has been my experience as well. But, I have had some people on this site swear up and down that the very early magnum 5.9s had a weighted convertor- I've never seen one, and I suspect they were mistaking a late roller LA for a magnum; but I also acknowledge that I can never say never- I haven't seen it all by a longshot.
