Has anyone had to fix the stiff legs on a G1 Chromedome. I'm trying to get at the inner leg screws because the feet assembly feel too loose, and could use a tightening, the red "underoos" on his waist seem to be holding the entire assembly in place. It doesn't look like anything significant is holding it in place, but it won't budge. I don't see a clip or a tab holding it in place either. I really don't feel like breaking an expensive part. Experts?
