Magnum flex plate 904 vs 727: identification?

If you buy the flexplate for a Ram/Dakota in the right years, the flexplate will already have the weights on it and you can use a neutral balance converter. I think mine came from a 99 Durango. Here is a like to what I bought:

You can see the magnum specific weights on the flexplate.
