I need to swap out the arms from a BT Alert with Alt Ricochet. (subaru molds) What is the best technique? I've been through the tutorials, but most start with the arm already off the body. It looks like I should I detach the entire wheel/arm assembly at the car, if so, how do I do this without breaking the joint. When I apply force it feels like the tabs will break. I tried heating with a hair dryer, but that didn't seem to help. Am I just being too gentle? I mostly worried about the arms on Alert, since I don't have extras of him. I figured this has been done a million zillion times so it should be easy.
