Sorry I don't have much pics for this step, I was on a working roll and you know didn't stop to photograph some things.
Basically I got the arm off and accidentally bend one part of the the case and it snaped off. So I ground off the adhesive and made it shiny. I then ground the rivet holding the parts in place and took everything out. Then I chose the parts I wanted from both arms and riveted them to the case. (Thanks armourkris for the instructable on that). Then I hammered the bottom where there was no parts inward, this made a nice grip for my hands because now all my fingers can go the same distance around the case.
