Want: Busted G1 Shockwave(s)

I don't care if it's missing it's barrel or a leg or two, or even has a busted hose, all I want is for the arms to be intact.
Or to be specific, I need the small grey part that connects the upper arm to the lower arm. It's a bit like an elbow joint.
Only need one, but two would be handy.
