So I bought an MP-09 Rodimus V2 at Botcon. Noticed a few days ago that one leg was looser than the other. The culprit was a missing screw on the back of the thigh (at the top of the orange part where it connects to the waist. Where is a good place to buy screws that small? I am pretty sure that they don't sell them at walmart/ target. Can't remember which dealer I bought him from but I know it wasn't tfsource or captured prey, and besides I'm not sure if the screw was always missing or came out recently as I've had him for a month now and he has been transformed many times. Any suggestions on where to find a replacement screw?
