>>11590539That's why you get one of these babies, a RadioShack Cold Heat soldering tool (and conical tip) as it directs electrical energy to heat ONLY the pin itself allowing you to pull the heads right off without melting anything like a normal soldering tool that gets hot. Like Classics Prime has a really annoying neck pin at an angle and every time someone wants me to make a permanent Parallax kit conversion I just remove the old head and keep it. Works for G1 figs, stripped screws, all sorts of metal-heat applications.
Swap away and take some pics!
