Basically did the same mod Peaugh used for the hand by reversing the fingers and shaving the peg. Removed the cannon from the arm by removing the pin.Cannon still connects to the old joint minus the pin for transformation. Put some glue in the tab to tighten it up Gave him fingers Dremel'd down the back of the seat so the hand stays during transformation. And this way he still has a hand and a cannon at the same time(cannon tabs in and the hand secures it). Just need to touch up the fingers. Quick and easy fix.
