>>10652909I also did go ahead and shave material off of the inside of the part of the shoulder connected to the torso. I just went in with a hobby knife and chiseled material away until it was as thin as possible. You do have to be careful not to shave off too much like I did on the left shoulder, or you'll get a little gap. But it's not the end of the world. Now the two parts of the shoulder don't clash into each other nearly as much and the shoulder lifts up much more freely. Haven't had the arms pop off at all since doing both of these mods.
