I just picked up Universe Sideswipe (a bit late on that I know) and everything about him looks great, but several joints/hinges on him are fairly loose. Most of these problems are easily fixed or don't bother me except for one. In robot mode, the door on his left arm just flops around. There's a screw there holding the door on, but as far as I can see it isn't accessible. There must be a way and I'm just missing it right? Anyone help me out here?
