Replacement shoulder block and hinge For 1/72 VF-1

The arms on my VF-1 won't Stay on AT ALL so I thougt of replacement blocks and hinge to fix it.The only "problem" with these replacement parts is that I took out the outward joint in the inner shoulder,But you can just use the transformation joint to fix that.I just mention it so you know what your getting.I don't have the actual replacements in hand yet,but I will get it and if any sanding or mods need to be done I'll put it in this description
