Thanks Chopper and Dmorja! I Emailed Cal just now. I'm just not expecting them to get back to me in a timely manner, since it took 3 years for the kit to deliver and communication with them is atrocious.
So I wanted to see what my other options were, and it sounds like I have many. My Mon Cal suit was too small in the torso, so it sounds like Colossus might be a good option.
