Mass shifting? LOL, one smokestack goes to the same place his trailer and roller go to. The beat up flat nosed truck in the movie had only 1 smokestack.
It's held on by just one screw. On the contrary, I'm hoping someone makes one for the left side of the cab.
Are you sure? What are those two red posts on either side of his head then? The same posts that some people are painting silver too?
Because theyre essentially the vestigial remnants of his pre AoE bot mode that either Hasbro, ILM or both, decided not to remove for symmetry's sake in bot mode. Its supposed to be those two red cylinders behind Prime's neck which have been constant with every incarnation of movie Prime's bot modw since '07... Must be why they're painted red to blend in instead of silver to stand out. Jya na!
Not that I can tell. The other side of the figure, where the other one would be connected, doesn't seem like it's holding anything together. And there's no screw there.
Your best bet is to probably file down or cut off one of them since they both seem to be connected together. Or make another smokestack.
