Hi, I bought a used g1 Devestator and im having a little bit of difficulty with it. I have attached the chestplate to a little nub that comes out of Hook(crane and Devestators chest), however when I look at the underside of the chestplate it seems like there are three places for a nub to go in, and a slot that is supposed to fit into the front of Long Haul(dump truck and Devestators stomach). The chestplate cannot reach, and would also angle if I tried to connect all these points. What is the correct way to attach his chestplate? thanks!
