I don't have one, but I can fix him for you. Send me your broken figure and 2 others that you don't care about, and I'll pull out the Rubber connector from one of the 2 donor figures and fix your Fisto. (The reason I want 2 extra figures, is in-case the rubber leg attachment part breaks during the removal process.)
Just pay shipping both ways. And when I'm done I'll send all 3 of your figures back to you.

... Or I can do the O-Ring fix as show here if you don't have any donor figures:
Thanks He-Bro. I will consider fixing the one that I have but am still on the hunt for a new figure as well. They are not terribly expensive so either way I will have my Fisto back.
