cheap vs expensive flexplate

the converter itself maybe balanced...but is it balanced for a 360...?

see the two weights between the drain plug...those are the weights that the 360 needs to be externally balanced.

or the newer one might have one larger single weight...

I am not sure about this, so, investigate further, but I believe the 360 L-A external balance amount imay be different from the 360 Magnum figure.

I'd check that out before I bought a balanced flexplate.
