>>7221693 the peg is too long. Your options are Frankenstein an acid rain ball joint thing onto the base of the neck (trying to make it look like just the collar of the shirt)
Or shorten the barbell. Which is hard but possible, I did it to fit a marauders head into one of these zombie lab guys. I cut the plastic drilled tiny holes in each ball with my dremel to put a metal "dowel"in there to give glue more to hold onto.
It worked out but I'm still not sure how fragile my neck joint is, so I don't remove his head in fear it will break and have a ball in each socket and no way to get it out
