Still need the magnum flexplate?

TrailBeast said

You would need either the magnum flexplate or a 360 balanced converter.
The balancer from the 360 works fine on the magnum.

That's what I thought,I just needed clarification from the experts.
When I got the car It had an LA timing cover, LA 360 balancer and 318 torque convertor and flexplate.
I knew it wasn't right.
Thanks for your help
