Help changing retro player's wingspans, shoulder width, etc?

When you try to change the appearanceinfo texts in the png files for players like Rip Hamilton, Hakeem, and other retro players there isn't an option to change any wingspan length(rightHand.ty), torso lengths(spine2.ty), etc. I need help changing these values.

Find a player who's body type you want to use. The legend's appearance should end with"Rigversion". Delete Rigversion. Now highlight and copy from the model that you are using everything from "Eye white" to the bottom. Now paste it into the legend's and save it and then you will be able to edit everything.
