Remove the hinges from the original shell. This is the most difficult step, as it requires a lot of force to remove the hinges.

Apply pressure with the pointed end of a spudger from the inside, pushing out with plenty of force. The hinges will likely fly out of the shell a few feet; this is normal.

Once the hinges are removed, remove the caps on the end of each hinge.

Be careful with the spudger. Pushing out the hinges requires a massive amount of force, and you might injure your hand on accident if you do not take extra caution.
