I ordered the parts from Allied Electronics, Inc
 
 

I created the interior bezel out of a piece of steel that I found in a hardware store. In order to position the "real" buttons in the center of each "external" button, I used the external bezel as a stencil. Using a ruler to draw diagonal lines, I found the true center of each rectangular external button. At this point, I drilled a hole. I wore out three expensive drill bits drilling these ten holes. Because of this, the interior bezel was a very expensive part to produce.

Once the holes were drilled, I bend the interior bezel to the correct curve. This was achieved by hammering.

The interior bezel is mounted on four bolts that are attached to the torso using the Reinbrecht method of gluing the bolts to the torso with epoxy.

In order for the "real" buttons to function, they must just touch the back of the "exterior" buttons. In order to achieve the correct contact pressure, I placed a spring over the bolts that hold the interior bezel in place. This spring pushes the bezel away from the exterior buttons and allows me to precisely position the interior bezel so that the "real" buttons can be properly depressed and released by the external buttons.
