trouble@hlj.com , e-mail them, ask for the VF-0A arm fixes, and get them to ship it to you, i'm not sure how much the arm replacements cost, you will need to buy a set (left and right arms). You must get them, otherwise if your shoulders crack and fall off, you will be dissapointed. There is a good chance they will crack, the only ones that have fixes are the VF-0S+Ghost combo ROY, and the VF-0A+Ghost combo SHIN (the line was half fixed).
