Magnum 360 to 904

I would recommend the 96 and up weighted flexplate which will work with any neutral balance converter. I got one from a salvage yard for $35. elongated the 1 hole with a rattail file and used a converter with no weights. I don't know if the 360 LA balancer will work with the magnum weighted flexplate . You could be looking buying a magnum balancer, surely someone out there knows......
