I'm finally getting around to opening some figures that have been sitting in their boxes for over a year and one of those was TFM Ironhide. Question for those of you who have transformed him. As soon as I swung his legs down, the top part of the cab popped off and I have no clue how to reattach. When you bring the head up, you kind of fold the cab behind him but no luck figuring out how to reattach at this step as well. Any help would be greatly appreciated. Thanks.
