MU Elbow Question

Posted in Custom Workstation

Hey guys, having a bit of a problem with a custom I'm making. I'm using an MU as a base (specifically MU Punisher), but need to swap out the lower arms. After much digging around in the fodder bins and thinking about what would be best, I finally found the perfect set. The problem, however, is that the lower arms have ball-joint style elbows, like the newer Hasbro Star Wars figs (specifically Thor line Odin lower arms). I have to use the upper arms from my base, so does anyone know the easiest way to integrate the lower arms? I would just start experimenting, but I really don't wanna mess up the arms as they're the only ones I've got that'll work. Thanks guys.
