I know they included a hip/waist replacement with their Blitzwing figure, but I don't have him. Is there anywhere I can get the hip replacement by itself? Thanks!
You can't get it from any vendor or the company itself. I went through this about a year ago myself. Best bet is to post in the BST "Wanted" section and see if you can find someone who bought the Gewalt/Blitzwing and doesn't own the DX9 Astrotrain so is willing to part with it. I did that and found someone willing to sell it for decent price. Just took a little bit but there are still people picking up Gewalts in the boards so it's not impossible to find. You could ask in that thread too and see if someone has one they don't need. That's really your best bet. DX9 D-08 Gewalt (Blitzwing)
I never used mine, and included it with the Chigurh I just sold so if the new owner doesn't want it, there may be one out there for someone who needs it.
