Does anybody know a good upgrade to make his claws articulated?

Just got the Spider-Man vs Doc Ock Train Scene in the mail, and it's great. Almost perfect. The one thing I don't like is the claws not having any articulation. Has anyone figured out any parts I can use to fix this? I can't think of any specific parts off the top of my head. submitted by /u/KL4W-TP [link] [comments]
