Are you sure your Hook is G2 or late G1 ("New Constructicons")? Because I can tell you now that your Scavenger is G1, not G2. The main differences between G1 "New" Hook and G2 Hook is that "New" Hook's hook is grey whereas G2 Hook's hook is yellow. New Hook also doesn't have the swivel-peg in front of the crane-operator's cabin around the mid-right section of the vehicle. It's the peg that connects Hook to Bonecrusher in the 1985 and G2 versions, but is absent in New Hook, since the New Constructicons don't form into Devastator. New Hook's purple is also darker than G2 Hook's.
