How is the Gasket for the Wall Mounting Kit 6SE6401-0WM00-0AA0 fitted to the MM411 FSB?

The MM411 Wall Mounting Kit was originally supplied with 2 gaskets. One was used for the Frame Size C and the other for the Frame Size B. It was found that the gasket for the Frame size C MM411 would be sufficient for both Frame Sizes.
