thats strange... all of the VF-0 shoulder problems seems to tackle the left part only...
also, does anyone know how to replace that round rubber stopper thingy inside the shoulders? after reconnecting the shoulders to the ball joints (treated with a mistakenly thick layer of nail polish), and twisting them a few times i decided to detatch them again because the joints were too stiff this time around - and much to my surprise the left rubber round stopper thing got "messed up" - wherein the it got torn apart from the ball joints being too thick.
