UV co-ordinates and values.

[dgud]

I don't see the problem really,
In uv-editor, select the charts (body-mode) you want to have the same position.

1. Move To/Top
   
2. Move To/Left
   
3. Move/Free
   
4. Tab and enter Dx and Dy
   

You will get your faces set in exactly the same position.
And if you faces are on different objects to start with, combine the objects first so it is one object.
